PLACE YOUR ORDER HERE!

Repetitive motions, awkward hand position, poorly set workspace and bad working habits can generally cause intense pain and stress on muscles, tendons and nerves. If you start having discomfort like tingling sensations, numbness and muscle pains, you should consult your physician.

That is why, keyboard makers are gradually learning the ways of ergonomics and apply its principles in their production of their keyboard and mouse products to help minimize wrist injuries.

1.) Properly Set Up your Working Space

- Your working space is going to be your place for quite a long time, so it is wise that at the start, you should take into consideration its arrangements, design, and space.

- Your keyboard desk should be at the same level of your elbow so that your arms will be in relaxed position while typing. 

- The mouse should be of the same level as the keyboard, so your desk width should be bigger.

- Level your desk in such a way that the upper edge of your computer screen as at your eye level or lower. 

- Put a comfortable distance between you and your working desk.

- Your desk should be wide enough to accomodate the keyboard and a considerably large space for your mouse to move about.

- Have your feet well supported.

- When working with documents, use document viewer or holder that you can place beside your computer screen to minimize the need to constantly swivel your neck and change focus.

- Allocate a space within reach for commonly used things.

- Things that are seldom used should be placed further away to avoid cluttering your desk. 

2.) Keep your Hands and Arms Relaxed or Comfortable as you Work

- Your hands should be at the same level as your elbow as you work.

- Your arms should be set apart a little, they should not be parallel or your wrists will have to turn when typing in the keyboard.

- You can use a palm rest, but use it only when you’re not typing or using the mouse.

- The areas beside you should be clear so you can take some time to let your arms dangle down towards the floor once a while.

- When typing in the keyboard or using the mouse, avoid supporting your wrists.

-Do not slouch or hunch. Sit properly, set your spine straight to avoid back pains.

3.) Establish Good Working Habits

- Maintain a work discipline all throughout. 

- Develop a routine and organization of tasks so that you don’t have to spend more hours working when you could have finished it earlier.

- Take short breaks to relax yourself.

- Establish a routine exercise for your wrists, arms, and head.

4.) Be Conscious of your Health

- Do not disregard symptoms of an injury to not make it worse. 

- If at any moment you feel pain, numbness or tingling sensation, have a break. If it gets worse, seek the help of a medical professional. You may have skipped your work for the day, but it will benefit you in the long run.

Keyboards unlike its predecessor, the typewriter, had reasons why it is invented for the modern age. Main reason is that of course it supports connectivity to the computer unlike the typewriter. Moreover, due to its compact design and portability, designers decided to pack the keyboards with more useful features to ease the navigation and computer interaction by users. Manufacturers realized that consumers are increasingly becoming aware of faster alternatives of doing things, same with using the computer through input devices such as keyboards.

The Function Keys

As the name suggests, function keys are designed to have specific functions built into each of them. One keypress for a function key is enough to execute a very useful command like ‘Help’. The function keys are generally located on the upper portion of the keyboard, directly above the number keys, beside the ‘ESC’ (escape) key. Although every application or game differ in their use of the function keys, they usually have similar uses on most function keys as I will enumerate below:

F1 – For desktop applications, this key generally launches the ‘help’ window or the ‘Manual’. It goes the same for games but sometimes it is also used to display the shortcut key mapping of the game such as in the game ‘Delta Force’.

F3 – Typically used to launch the ‘Search’ bar, so that the user can find for a specific word in a page, such as in browsers.

F5 - Typically used in games, a short cut key to save a game state, also known as ‘Quick Save’.

F6 – Still used in games, the opposite of F5. F6 is used to load a game state, also known as ‘Load Quick Saved Game’.

F8 – Globally used to activate Dual Monitor or LCD Projector if supported by the hardware and operating system. 

All else varies widely from application to application.

System Keys

The ‘Ctrl‘ or Control key for the PC, or Command key for the Mac, the ‘Enter’ or carriage return key, the ‘Alt’ or Alternate key, and the ‘ESC’ (escape key) are part of the system keys. What they do is that they are used to execute extended commands for a given key. For example,’Ctrl’ + C, which is used to copy to buffer the highlighted text or file. ‘Ctrl’+ V to paste whatever is stored in the buffer, ‘Ctrl’+X which is cut which is similar to copy and paste but the source is deleted.

The ‘ESC‘ or escape key is used mostly to exit applications or show the exit menu. It is also used to cancel a currently running command or pending command.

The ‘Enter’ key in turn is used to execute commands or launch an application. It also serves as carriage return in text editors.

The ‘Alt‘ key is also used to execute certain functions. The ‘Tab’ key is used to enter long spaces in a text editor. But if used simultaneously with ‘Alt’, it switches the active window to the second active window and vice versa. ‘Alt’ key is also used to enter special characters unavailable in the keyboard by using with it a special sequence of numeric keys such as ‘Alt’ + 0 + 1 + 5 + 3(Note that the numbers must be inputted from the numeric keypad), the result is ™(Trademark). Give it a try! 

Text Editor Keys

‘Tab’, Space Bar, ‘Shift’, ‘Backspace’, ‘Home’, ‘End’, ‘Page Down’, ‘Page Up’, ‘Insert’, and ‘Delete‘ keys belong to the Text Editor Keys. These keys are generally useful for word processing softwares.

As you already know, the Tab key inputs multiple spaces.

The ‘Shift’ key forces the uppercase letters of a pressed lowercase letter.

‘Home’ forces the cursor in the text editor and places it before the first character in the current line.

‘End’ performs the opposite, forcing the cursor after the last character in the current line.

‘Backspace’ deletes the first character before the cursor.

‘Delete’ performs the opposite, deletes the first character after the cursor.

‘Page Up’ scrolls the page upwards, while ‘Page Down‘ scrolls the page downwards.

Typing fast on the keyboard is not an easy task. That task is harder than it looks, but it is not hard to acquire this ability. Yes, it can be learned! This amazing ability is just as important as any other skill an employer would like to see on an applicant’s resume, equally important as a proficiency in a programming language, business know-how, interpersonal skills, managerial skills, etc. This is the kind of skill you do not want to be left behind about. Why is it so important?

The Importance of the Talent with the Computer Keyboard

Let us bear in mind that we are now in the “Computer Age”, the era governed by electronic gadgets, where tons of information circle around the globe in a matter of seconds, where data are constantly transferred from one medium to another, where almost transactions involve computer interface. Interfacing or interacting with the computer has many forms, from image captures, microphones, scanners, mouse pointers, to the most old and common, using the keyboard. This device, the keyboard is the most indispensable computer input unit since it allows you to issue commands to a computer, lets you perform data entry, textual communication, programming, writing journals and so much more. 

Some keyboards, especially specialty keyboards and some industrial keyboards have braille code embossed on each key. Braille is a pattern of dots each represents a character. This system is commonly used by blind people to help them to read. Many books now have been published on Braille, and blind people can read their content just by touching the pages just as a normal person would read the text from left to right. Now, Braille had found new uses and applications and have already been incorporated in many industries. It is important in dark environments where backlighting the keys aren’t possible for some reasons. Most Automated Teller Machines are also equipped with keypads with Braille on each number.

Sadly still, there’s still no technology yet available to enable blind people to read the computer screen, so Braille on keyboards are used mostly for industrial and commercial reasons. 

Braille can also help keyboard users gain training and speed on typing on the keyboard since they are trained not to look at their fingers while typing instead they have to look directly on the computer screen, a crucial step towards learning how to type fast on a keyboard.

Most of these applications are geared towards business, so when we talk about business, we talk about efficiency and speed. Now, how can these be achieved when the keyboard user is slow? It is obvious that business owners would hire those who will help them save bucks, those who are fast typers or encoders to increase the speed or volume of transactions per unit time. A fast typer will always have the advantages a slow typer  does not have. But how do we define a fast typist? In what sense can we tell that a person is a fast typist?

Words-Per-Minute

Fast typing is usually measured with words-per-minute or average WPM. Most computer literate people have average WPM of 15-25 while programmers and data encoders need to have about 60-70 WPM. Article writers too need to have the proficiency in handling the keyboard. This means that when typing, they should be well versed already to the layout of the keyboard and can type without looking on the keys. This saves a lot of time than having to look or edit the entry everytime a word is typed because of typographical error. Article writers and programmers for instance must utilize their time on the code or content rather than spend a percentage of their attention to the keyboard. So how is it learned? How long can it be learned? Is it really feasible? 

Fast Typing Training

Those who are born in the computer age, the young ones, the new generation always have the advantage than their older non-techy counterparts since the new generation seem to have an affinity with electronics automatically at birth. They learn fast, but still, older ones can keep up! 

Anyway, you would be lucky when you have already started typing since you were young because chances are, you have already gained enough muscle memory in your hands to make you a very fast typist. If you just recently started using computers, it would be hard for you, but still, everything’s possible. If you want to be an article writer, or a blogger, or a researcher, you need to focus on these. So how do we do it? Here is the basic steps:

The Guide to a Faster Typing

1.) Position your hands to typing position. When saying typing position, put your left hand fingers on ‘a’,'s’,'d’,'f’, from pinky to pointing finger, then the right hand fingers from ‘j’,'k’,'l’,';‘ keys from pointing to pinky. We don’t assign a key to the thumb since it is not accurate and strong enough for fast typing, but it can be used for space bar. 

2.) Since you already have your position, when typing, avoid crossing your left hand to the right side of the keyboard and the right hand crossing to the left part of the keyboard. Avoid crossing since it will only jam your fingers when you’re attempting to type really fast.

3.) Do not use the thumb to press ‘Enter‘, just use whatever finger is nearest to it, again no cross overs. 

4.) Start by typing your full name repeatedly, including the names of your loved ones, gradually, until you will be able to type these without looking at your hands. 

5.) Start copying entries from books and encode them to a word processor or text editor program such as ‘Notepad‘,’ Wordpad‘,or ‘Microsoft Word‘.

6.) You will be amazed how muscle memory can easily remember the layout of the keyboard with all its 88 keys.

7.) You can make use of typer trainers such as ‘Typer Shark‘ from PopCap games. It is challenging at the same time rewarding with what you achieve after every other session.

Ok, you have your keyboard now. Whether it is included in your CPU casing package bundled with the speakers and a mouse, or you bought it specifically for its brand and features, but let’s assume that it is wired, whether ps2 or usb. 

Now, expensive or not, if you’re a responsible owner and cares for the environment and thinks to those other people who don’t have enough money to even have a personal computer at home, then you would value whatever things you have even if it’s not that expensive. Then how would you show that you are grateful for what you have? Of course, by taking care of your things, in this case the keyboard. Let’s start by preventing damage through maintenance and precautionary measures.

First of all, you do not want your keyboard to become like this, an ecosystem infested object:

 

Here’s the top list of things to do for prevention of damage to your keyboard:

1.) Do not eat in front of your computer, especially those with crumbs like bread or biscuits. Because once that it gets inside your keyboard, it will attract an army of ants and they will build their new colony inside your keyboard, that’s what happened to mine before. Once they build inside, your keys gets harder to press and its response is hampered when the ants start eating the rubber-like material inside or the membrane. Yes, the ants will eat that kind of rubber since it is ideal for their food to stick to, the scent of their food will adapt to it giving them the impression that it is part of their food. You wouldn’t want that.

2.) Before touching the keyboard and mouse, wash your hands and apply soap too so that the grease in your hands will not be mixing with your sweat and transform into a yucky cocktail of mud that sticks to your keys and mouse. It also attracts insects since they are fond of dirt. 

3.) If your hands are sweaty, always prepare some kind of cloth to wipe your hands into when it gets sweaty since water such as sweat that gets inside your devices damages the circuits or the PCB overtime, the same principle that applies to your cellphone that is why it is not adviseable to place your cellphone in your side pockets when your legs are sweaty.

4.) When someone else was using your computer before you do, wipe the keys first with a cotton and alcohol solution, also include the mouse to make sure that no dirt had been left. It sounds harsh but it is just a precaution. Also it breeds bacteria overtime if you don’t do it routinely.

5.) Practice typing softly. This reduces the stress undergone by each key therefore extending its lifespan. Typing softly can be achieved by training your hands to type fast and in turn, fast typing can be achieved by training how to place your hands properly specially made easier by ergonomic keyboards. You can also make use of typing trainers such as the Typer Shark game. Kill the habit of hitting the ‘Enter’ key like it’s a typewriter(most people do it, especially computer gamers who have been typing in a trash talk and excited to deliver his punchline unto the other player).

Basically you can get away good with that. But for a better assurance, let’s clean your keyboard!

(Caution: Most keyboards are not waterproof so this one in the image doesn’t apply, yet some kinds of keyboards such as waterproof metal industrial keyboards are waterproof and can withstand any type of element applied to it)

Here’s a few tips, mostly from own experience, from basic to survival.

Top lists for cleaning and opening a computer keyboard:

1.) You can use a cloth or cotton with alcohol solution on it to wipe your keys clean and reach for the corners and in-between keys. You can do this daily.

2.) For dust that has settled already that cannot be removed by cotton, you can use a small brush like the one used in painting and use it with a vacuum. Do not attempt to use a blower unless if you’re opening the keyboard itself. Alternatively, you can do the same as shown below. Using a gel like this will make dusts stick to it easily.

3.) Ok, you decided to open your keyboard to eliminate the colonies in there so hang on. Prepare some cotton swabs with alcohol solution, know that when ants store their food, they secrete some kind of liquid to it to make it sticky, maybe to preserve it? Yes, right now, there will be a sticky substance sticking to the inside membrane of your keyboard. Turn your keyboard upside down.

4.) Unscrew all the screws while maintaining upside down position. Safely keep the screws. Remove the lower cover of the keyboard. By this time, you’ll see the membrane of the keyboard that looks like rubber. Note that some keyboards dont have membrane style. The membrane inside requires you to unscrew it even further. But before taking it away, note that under the keys, between the keys and the membrane are rubber domes that act as spring when you press a key. They are tiny numerous things, keep them safely.

5.) After you kept them, you can proceed to remove the membrane after you unscrewed it. Just remember the order with which you started because it will be the same order when you reassemble it all back in place. 

6.) Now you can start eliminating and cleaning!

7.) After you’re done, place the rubber-domes carefully inside every key then place the membrane on top of it making sure that the metal contacts are directly over the rubber domes. Screw everything that you unscrew before, and you’re done! 

Remember that opening your keyboard was the last resort, it is not always a guarantee that after you assemble it back in one piece that it will work perfectly, sometimes mistakes can be made so be careful.

Some images speak a thousand words, just look at these images and you can see how most keyboards look in the inside.
