Has anybody found a good way to make the standard "Undo" command apply to specific scripted routines?
It seems pretty straightforward to store the "status quo ante" situation, and catch an undo command that would put things back. The problem is how to make that option expire as soon as it should. Certainly I'd want the undo-this-routine option to disappear if the user has since done something that Metacard itself makes undoable (like typing in a field); or if the user has gone to some other card. Is there a reasonable list of system messages that might be intercepted and taken as signals to "clear the custom undo buffer"? Is there some way to detect when MC's own undo option (for its own undoable routines) has become (or whether it remains) available? Thanks for any thoughts.
