>I'd like to have a KEY that simulate the bottom... I don't know how can I do this...

I would do it this way, remove the code in your KeyPress(), and then set the "Default" property of the Save button to .T. Now, instead of F8, have your users press Enter to hit the Save button. This will fire both Valids like you want.

Otherwise, if you want to keep F8, change your KeyPress() code to this:

If nKeyCode = -7 && F8
	ThisForm.Save.SetFocus()
	ThisForm.Save.Valid()
EndIf

So focus moves and the Textbox's Valid() will fire
