One-Handed Typing on your Mac keyboard!
A one-hand keyboard layout designed for former two-hand touch typists.
Holding spacebar "mirrors" the keyboard. Now you can type all the keys with a single hand.
The keys that are normally on the right side of the keyboard are now on the left, and vice versa.
But the mirrored layout still uses your normal touch-typing muscle memory. Each key is typed with the same finger and is on the same row. The only difference is that youre using the other hand.
Mirror-QWERTY is the best way to type with one hand if you are already a two-hand touch typist.
