I sometimes use Ctrl+w (yank the last word) then Ctrl+y (paste it) in terminal.

Ctrl+a (move the cursor to the beginning of this line — useful to add sudo)

Ctrl+e (move the cursor to the end of this line)

Ctrl+f (move the cursor forward one character)

Ctrl+b (move the cursor back one character)

Ctrl+u (yank the whole line — better than hitting backspace a whole lot)

Ctrl+l (clear the terminal)

Ctrl+d (logout/exit)
