User Keys sometimes effectless?

[Han]

I understand your post as asking how to create a user key that behaves like a built-in key action -- is that correct? If so, by simply having your user-defined key program return the key number, it will then launch the default key behavior. So you can create a program and have it do whatever you wish, and then simply have a RETURN(key_value) command to have the last action be the action of the key associated with key_value.
