[[ I got perfect answers to my original questions about undo, the another questions is probably neglected, so I split another thread.]]
In VIM, I can input <ESC>...comand<Enter>, in Acme I have to move cursor to command area and click, input command, press <ESC>, click middle mouse button on the highlighted command, is this the fastest way to input command in Acme? I'm not arguing Vim is better, I agree some operations are faster in Vim and some faster in Acme, I just want to know the most efficient way in Acme. Thanks in advance for your kindly help!
