You seem to have the PickFirst=On event thing figured out.
If PickFirst=OFF, use the BeginCommand event. To interrupt the command use
a SendCommand with the Esc character; in AutoLisp it's (chr 27). This
procedure will probably work only on the commands that require additional
user command-line input. "Quit" is a typical command where it won't work.
