Only Give An Error Warning If Enter is Pressed

When entering functions I'm finding more success if I complete the function in it's entirety, then add the values/ parameters.

e.g. IF( , , )

I then hit the back arrow to start entering the arguments/ parameters and I get an error warning and it's crushing my soul and chipping away a piece of me every time I hear it; also slows me down.

Microsoft please change this in Excel 2016.

Lol my apologies, that's embarrassing.
