One Hand Typing

No Comments

If you have to type with one hand, AutoHotkey is a free option to turn your regular keyboard into a half mirror keyboard, where each key on one side is mirrored to the other (activate it by pressing Space key first).

Here’s a script, copied from AutoHotkey forum with slight modifications:

#SingleInstance, force
; Half-QWERTY: One-handed Typing - version 3a
; http://www.autohotkey.com/forum/viewtopic.php?p=228783#228783
;
; HalfKeyboard invented by Matias Corporation between 1992 and 1996
; Originally coded in AutoHotkey by jonny in 2004
; Many thanks to Chris for helping him out with this script.
; Capslock hacks and `~ remap to '" by Watcher
; This implementation was done by mbirth in 2007
;
; version 3a script, mod by hugov:
; 2008-10-31:
; - mixed with "Capitalize letters after 1 second hold" at request of Calibran
; http://www.autohotkey.com/forum/post-228311.html#228311
; just tested very briefly so try at your own peril :-)
