1st, this is the wrong forum for questions as this is "amples and tips".You should have posted in "Question & Help needed".
Anyway, regions are user definable...I mean you can create a sub and call it form (Sub Form....End Sub) and automatically the editor puts a minus sign to the left of the first Sub line, enabling folding the sub...
But maybe this was not what you meant...
If you are refferring to a region were you could define a p+articular form properties, the I guess there not a direct way, but you coul create a sub and call it from app start...
