If you touch-type QWERTY you already half-know Colemak.
Many of the keys stay the same, which means many of your shortcuts remain the same. On a Mac, these shortcuts are Undo, Cut, Copy, Paste, Bold, Minimize, Hide, Quit and Close.
The keys that do move don’t go far, usually one or two keys away. Mostly we’re trying to get the common letters on to the home row and move the uncommon ones away. Many keys that move stay on the same finger, or at least in the same hand. Only E and P swap hands. In Dvorak, 22 keys swap hands.
The punctuation keys don’t move, except for the colon/semicolon (no way that gets to stay on the home row!) In the Dvorak layout, all of these punctuation characters move: fullstop, comma, question mark, single quote, double quotes, square brackets, curly braces, angle brackets, dash, underscore, plus and equals. It’s a nightmare for programmers!
If you were to scratch off the keys that have moved, look how many you’d have to remove for Colemak compared to Dvorak:
As if you didn’t know, QWERTY is inefficient. Dvorak is a lot better, but Colemak is by far the best. To prove this point, here is the heat map of typing this very blog post on QWERTY, Dvorak and Colemak:
There are other reasons here to explain why Colemak is easy to learn.
With the holidays coming up, do your future self a favour and learn Colemak!
