I think you do great work. But let me tell you about user friendly keyboard.

I don't know what layout you have on your keyboard. On my Swiss keyboard

Shift - all the way to the left on bottom row
Strg - all the way to the left on top row.

I just dont find a way to press these two buttons with two fingers of the same hand without making strange faces. I guess my fingers are just to wide.

And if I use fingers of both hands I miss my third hand to hit the extra key.

Am I the only one with this problem.
