New Record -- special script

Yes--but can't say much more without knowing more about what you want to do and the structure of your database.

The general answer is that you would set up a script to do both create the new record and to populate the appropriate fields.

Howdy firth,

Buttons are layout specific.  Have the button on that layout perform a different script than on other layouts.

If using a shortcut like Ctrl-N, use a trigger to look at the layout { Get(LayoutName) } within an "If" loop and define your actions based on the layout name.

I assume that this is enough direction and you can fill in the blanks.  If I assume poorly, please say so.
