"Here, are a few useful candidates. (C = control key, M =
alt/meta key.)
C-r and C-s : Launch an incremental search backward and forward
(respectively), in your command-line history.
C-j and C-g : Abandon an incremental search either with the line

M-. or ESC then . : Both of these insert the final argument to
the last command at the cursor point. This is useful when moving
files around and editing them."
