Does anyone know how within a certain form I have use the F4 key or one of the F keys to fire a DoCmd.OpenForm event? Also when this occurs it will open a form. I need to somehow in that form know that this was hit, because the same form opens up as non-editable on the same form. Anyway I can do this? Thanks

Look for help on SendKeys / AutoKeys although you should be aware it's success is not always guaranteed.
