Alt-. is in bash. I use it dozens of times per day, and its best feature is pressing it repeatedly to get arguments from earlier commands. Also if you press Alt-<number> before it, e.g. Alt-2, it inserts argument 2 (or whatever) from the previous command (0-indexed).
Alt-q isn't in bash, at least by default, but it sounds pretty useful. I accomplish a similar thing with Alt-#, call the (now commented) command back with Up after however many other commands, then Alt-3 Alt-# will uncomment and run it (any number works there, but 3 is on the same key as #.
