Pay in Full F3 slowing me down.

SOLVED

Hello

I have taken on the very latest version 25 and am a touch typist, using Sage since the late 1980's.  I find it slows me down having to take my hand off the key pad to go up to press the F3 key to pay in full.  I have looked at the shortcut keys entry in the help sections, and can see there is useful information there.  But as the F3 key is a shortcut, it gives no alternative. 

Can anyone let me know if there is a way of pressing pay in full using the 'Alt' key, as it is very frustrating for someone who works very quickly in sage and is used to pressing Alt P who now has to go up where there is usually paperwork strewn around the top of the keyboard, to find the F3 key.  Is there an alternative.  

Many Thanks.
