Please provide additional edition shortcut
We've already got C-a, C-e, C-k and C-w, but it would be nice to have additional standard shortcuts:
* C-u to erase the text at the left of the cursor (or the whole line, I think both behaviours are common)
* M-b/M-f to move the cursor one word left/right
* C-b/C-f to move the cursor one character left/right
* C-y to paste what was just cut with C-w, C-k, C-u and friends (very useful when you start typing something, then want to answer what was just being said prior to send your answer)
* there are other shortcuts common in shells and other text-based programs that I don't use frequently but would be nice to implement for those who are used to them
Also C-u is very common in password fields, that allows to restart typing your password when you know you've made a mistake, so that would be nice even in other frontends.
