gmaxey,
Is it true, with your code, -to choose the next macro number, the operator would do one of these:
A. use the keyboard to enter one or two number and click the OK Button.
B. use the keyboard to enter one or two number and depress the ENTER KEY.

Either way is ok; because sometimes my hands are situated to use the mouse and sometimes the keyboard is quicker.

But it would be even better if the Input Box, (or Dialog Box), would allow a Shortcut Key, something like:
Ctrl + x or Alt + x or Ctrl + Shift + x
Ctrl + a or Alt + a or Ctrl + Shift + a
Ctrl + b or Alt + b or Ctrl + Shift + b
about 25 different ones like this!

Because I can keep my little finger on the Ctrl Button by habit. And then to depress only one other key is as faster than you can say USS Gerald R. Ford.

This may sound silly, but when I get in a good rhythm, depressing three keys instead of just one seems very cumbersome and slow as molasses. And a required mouse-click when my hands are flat on the keyboard seems cumbersome indeed.

I have been looking and I can't find any way to do this. Perhaps you know of a way.
