I should have said "Notwithstanding DreymaR's earlier comments (I don't care too much about Windows shortcuts), can someone suggest a reason not to use it?". As a Unix geek, the shortcuts I use more are ctrl-C,-S,-Q,-Z,-L and the ubiquitous Emacs keys: ctrl-A,-E,-N,-P,-K,-U,-B,-F, most of which have changed in Colemak anyway. I'm a vim user but Emacs are the default in bash so I learned them too. Shai's "Important keyboard shortcuts" are too subjective for me.
Perhaps it's also worth re-iterating that I don't use the "standard touch typing technique" nor does my comparison. ALL of the testing was based on a technique that the entire left hand is also moved one key to the left (for the bottom row only) so the same fingers will be used in Kolemak as would be in Shai's testing of Colemak (except Z is now on the index). In other words, qwerty X (now kolemak C) is hit by the middle, not the ring finger.
For the same data set, my qwerty results will be different to Shai's qwerty results because of the shift in fingering.
What I am really looking for is for someone to say "What about the di/trigraph '...' (whatever) which occurs so frequently?". But as I'm shifting both the finger and the key it hits, I don't think there are any.
I don't know where I got the name Kolemak from - it was either here on the forum or a site that links off it. Maybe I'll call it Cuulemak for Unix Users :)
Yes, it's a very subjective data sample - it wasn't meant to be a deep introspection - just a cross-check of "Is colemak really the right one for me?" Maybe it still is. There are lots of things the applet can't test, such as Backspace, Tab-completion, 3-key combos like Shift-Ctrl-Whatever, auto-indenting, code justification/completion/correction. Does anyone have a more sophisticated algorithm that more closely simulates a human user? ie. Unix geek?
I'm not here to fight it to the death, I'm just sharing my findings in case anyone else stumbles across this thread and wonders the same thing. A friend of mine who is about to start the Colemak journey also shifts his fingers on the left bottom row, so I know I'm not the only one, +sorenk(?).
Either way, there's no going back for me, so thanks Shai, for making it so much better than QWERTY and easier than Dvorak. The plethora of drop in files available here has made it really easy.
