Oh, ok -- I wasn't aware that there had been extensive usability tests on the keybindings you mentioned?
The (obvious?) point was that neither have such backing.

Much more RSI is caused by relocating your hands continuously, IIRC. We type combinations in most sentences. Where do you get the idea that control-A runs the risk of RSI more than relocating twice?
Depends on where your hands are when at rest (which I guess depends on whether you've had 'formal' keyboard training or not)
Do you rest your hands over the nav' keys?
and just how often you need "start of line". [...]
More than I need to select all, for sure. Control-A isn't far from Shift-A and no-one complains about that being particuarly bad for RSI.

This is not the same as "let's junk all our past work and injure existing users," though.
Nope, but then I've yet to see any evidence in favour of ^U, ^K, ^Y, ^T, ^A, ^E, either.
These are fairly language-independent: A is the first letter, moving you to the first letter K are the scissors cutting forwards Y is the pasting tool T is similar to a proof mark for transpose
I admit that I can't remember whether U and E were intended in this pictographic way, or just accidents that caught on. It's not possible to justify "select All" other than in English, is it?
