Button rack or hotkey function - OldMoses - 07-20-2022
Been working on a new version of my grain harvest database, and while building a support file editing section, I conceived of the need to quickly and easily display a row of button choices, along with the ability to accept hotkeys in lieu of mouse clicks.
It depends upon a few of my other library routines (included in the code), but anything could be easily adapted. I'm particularly indebted to Steve for his MBS function and SierraKen for his beveled calculator button algorithm.

LOL cool buttons. B+ gave me your Clear_MB Sub the other day for my calculator, thanks! I posted an update to it today with a fix.
