everything after ":" in the above line is what you want to do, $1 is always either "begin", "end" or a number in $submenu, unless $popup() (or any other alias you choose to use) uses /tokenize.
So:
return $read(<file>,$1) $+ :
That makes the popup name
echo -a $read(<file>,$1)
Is what you want the popup to do when you click it.
