Earlier quoted context omitted.
Cmd + left/right works everywhere for me (except the terminal)
And for those unaware of Cmd+left/right, there's also Alt+left/right for moving over one word at a time.
And terminal has ctrl+a and ctrl+e. My mnemonics: A is for Anfang (german: start, beginning), e is just End.
On windows I was confused as to whether Pos1/End gets me to file ending, or line ending. I think it's the first, unless you hit a modifier key.
