One-hand typing

Benefits and drawbacks

One-handed typing can be useful in situations where one would usually need to move their dominant hand between one's keyboard and mouse or if the typist's hands are otherwise occupied.

A potential drawback of this method is that it can be straining on the typist's hands, which can lead to repetitive strain injury.

Mirrored keyboard

Main article: Half-keyboard

The idea is to only use one hand (preferably the left one) and type the right-hand letters by holding a key which acts as a modifier key. The layout is mirrored, so the use of the muscle memory of the other hand is possible, which greatly reduces the amount of time needed to learn the layout, if the person previously used both hands to type. This was first devised by Edgar Matias et al. in 1996 and later referred to by Randall Munroe on his xkcd blog.

Hand home position on FGHJ

Using a standard keyboard, the one-handed typist must move from side to side to cover all the keys. Ideally, this typist should keep their main hand on FGHJ, but they will inevitably be forced to leave the home keys or stretch like a concert pianist to reach all the letters. Without using a second hand as an aid (for example, the right shift key), most capital letters require a time-consuming excursion to one side or the other. This reduces efficiency and frustrates the typist.

Special keyboard layout

Some single-hand keyboard layouts exist, such as the "one-handed Dvorak" and the "left hand Ngaih".
