vi - Vim "show my last command" command?

Question

Is there a command which shows what was the last command in normal mode?

Suppose I accidently hit random key and got some unexpected result. Sure I can undo it, but could I reveal what key was pressed and how it was interpreted?

Answer 1

Hit the colon (:) and then use the up arrow to start going back through previous commands. You can use the up/down arrows too to move around the list.
