Typing on a computer keyboard involves using either a touchpad or a pointing device, to click and type on the keys. The earliest computer keyboards were not touch-typing devices but those made specifically for use with a mouse. The earliest type of computer keyboard was a sort of typewriter, with a "k" shaped keypad and large flat area to press the keys. The keys were usually grouped into seven basic classes, all of which are still used today.

The obvious purpose of a one handed keyboard is to use just one hand to type, or at least type with just one hand. It is much more comfortable to use than a regular keyboard and is very common in typewriter keyboards and laptop computers. The earliest models of one-handed keyboards were quite mechanical, using springs to keep the keyboard pressed when you typed. Its use has been replaced by more modern mechanisms based on rubber or gel-based plastics.

Another advantage of the flexible keyboard is its easy and flexible operation. You can easily change from one layout to another without having to disassemble or reset the keyboard. Even get a completely new keyboard if you need to. One can even get a completely new layout that works very well with all the other computer hardware you have. This kind of wide-ranging compatibility makes it very popular with people who use several different types of computers and operate several different operating systems.

The other great advantage of the flexible keyboard is that the actual physical keyboard has a tactile feedback to provide you with a tactile feeling as you type. In the past, most keyboards provided no tactile feedback at all, but these days you can find some that come with a very sensitive and responsive tactile feedback mechanism built into the keyboard. This means that you can actually feel each key and precisely which key is being pressed. This is especially good for people who are new to using computers and who spend hours at a time typing messages and taking part in computer gaming. With the tactile feedback, you can be sure that every keystroke you make is registered and hit.

One of the most popular and least appreciated keyboard feature is the one-handed keyboard feature. The one-handed feature provides users with the ability to type with both hands free. With two hands free, users are able to operate with greater precision and control. This feature is particularly useful when you are playing computer games where you require accuracy, timing, and precise targeting of keys. It is especially helpful when your hands are full and you are typing quickly. In this scenario, one-handed typing is a huge advantage.

One of the drawbacks of a one-handed keyboard is that you can not use any of the other three input methods. For example, if you use the mouse for input then you will not be able to use the trackball or the scroll wheel with the one hand. You can also not use any of the other input methods while the keyboard is in use. The only option left is to either lower the keyboard's sensitivity or move the mouse to find alternative keys. Some people find this awkward, but it is a small sacrifice when compared to the benefits it offers.
