Windows 10: custom keyboard shortcut for Undo and Redo

I have a program in which I use the "Undo" keyboard shortcut of Ctrl-z, and the "Redo" shortcut of Ctrl-y, dozens of time daily. I am a poor typist an it would be much easier for me to have a single key shortcut for both of these functions. Is it possible to customize Windows 10 keyboard shortcuts to do this?

I am using Windows 10 home version 2004

Thanks

Undo & Redo

I have deleted some files by using Undo (Ctrl+z) on my desktop by mistake, how can i recover this files ? Redo didn't work

 

How to ReDo multiple times? To correct accidental multiple UnDo's?

First Post - How do I essentially Reverse the Back Arrow Undo function? (Button in upper left W10 File Manager).
The adjacent Forward Arrow Redo button only seems to Re Do 1 step. But I want to Redo several accidental UnDo's.

Using W10 File Manager, I downloaded 33 jpg pics from my LG Android cell phone to a folder on my PC laptop computer, then Deleted the 33 pics from cel phone. All good far, I have the pic files on my laptop.

I then Resized the pics & accidentally also created Shortcut. This created 33 shortcuts which I did NOT want.

Rather than just (tediously) select & delete the 33 unwanted files, I instead Back Arrowed to Undo the creation of the shortcuts.

However in a moment of brain freeze, I accidentally clicked the Back Arrow 3 or 4 too many times, which also undid the resizing,
undid the import transfer of the files from cel phone into a new laptop folder, and the steps before that of creating the new folder in the first place.

So 'logically' I no longer have 33 pic files on my laptop.

Trouble is, after I originally did the import transfer to laptop, & intentionally deleted the 33 pics of the cel phone, they are no longer on the cel to Re-Transfer again. I 'lost' them.

So how do I essentially Redo (Forward Arrow) multiple files?
Or is there another way to recover these files?
They are NOT in laptop Recycle, nor in Photos on cel phone.
