To be execute on bash or zsh, as far as I know

Go to the end of the line: ctrl+e

Go to the beginning of the line: ctrl+a

Move by one letters at a time: ctrl+f (ctrl+b to go backwards)

Move by word alt+f (alt+b to go backwards)

Delete words: alt+d (remember that you need to be in the beginning of the word)

Update (thanks to @etagwerker)

Shell History Reverse Search: ctrl+r Start typing a previous command and it will look it up for you, so you just press enter without having to write the whole (long ass) command again.
