Hunt and peck

Hunt and peck (aka two-fingered typing or peck and run) is a common form of typing, in which the typist must find and press each key individually. This is almost always considerably slower than touch typing. Instead of relying on the memorized position of keys, the typist must find each key by sight. Use of this method may also prevent the typist from being able to see what has been typed without glancing away from the keys. Although good accuracy may be achieved, any typing errors that are made may not be noticed immediately, if at all. There is also the disadvantage that because fewer fingers are used, they are forced to move a much greater distance.

There are many idiosyncratic typing styles in between "hunt and peck" and touch typing; for example, many people will type blindly, but use only two to five fingers, and not always in a systematic fashion. Some people have developed advanced forms of hunt and peck that don't require looking at keys, or losing too much speed.

Thumbing

A rather new trend in typing, primarily used with devices such as PDAs with built-in keyboards, is thumbing or thumb typing. This can be accomplished using one (e.g. phone keypads, Palm Treo 650) or both thumbs (e.g. HTC TyTN, UMPC DialKeys, Nokia 68xx series). Similar to desktop keyboards and input devices, if a user overuses keys which need hard presses or/and have small and unergonomic layouts, it could cause thumb tendinitis or other repetitive strain injury.
