The menus are contained in a stack called "revmenus". You can either access
this stack in the App Overview, or use a statement like the following in
the message box:

  edit script of button "File" of stack "revmenubar"

(substitute whatever menu name you want to look at for "File")

I assume you're puzzled about the second line. In chunk expressions, a
minus sign means "from the end" of the string, so "line -1" of something is
the last line. (Other examples: "char -2" is the second-to-last character,
"item -4" is the fourth-to-last item, etc.)

"select line 1 to -1" means "select all the lines" of the target field.
