OK Maxim, thank you for that. I read the post, but I don't understand if I will need to edit the MenuGroup.cui file as well, or just use it to view the exact spelling for my new MenuMacroIDs (the commands I want to remap to my keys). The post seems to tell me only to check it out and see how commands are listed with the new shortkey configurations after I edit the AcceleratorRoot.cui file. Also, my initial confusion when I opened the AcceleratorRoot.cui file you sent me is that I find "F2," for example, in 2 separate lines of code, and I am not sure which one to edit. I'm going to assume that it is the second line that contains F2 because it is inside the container "<!-- Custom -->".  I have attached 2 screenshots to clarify what I mean by this reference to the code. Second, I understand when wanting to code the non-character keys, I can type "F1", "F2", "F3", "F4" ... etc for function keys, and "SHIFT", "CMD", "ALT", "CTRL" ... etc for the modifiers, but do not know what the text is for other modifiers. The third image I have attached has dashed orange lines around the keys which I do not know how to type the abbreviation form for in the code; can you please provide this too? Third, can you clarify why it is not possible to remap the other function keys (F6 ... F12)? Fourth and lastly, your post ends discussing how to program the double click to launch a command. I have the Contour Unimouse (https://www.contourdesign.com/product/unimouse/) which as you can see in the link, has 5 click buttons and a scroll button which is also a click button (so 6 technically). How can I program double or triple clicks on each (and also see what each is set to in single clicking)? Thanks for being patient with this long response/request.
