Since this is a productivity mouse, I think it should enable more complex keyboard combinations.

In many programs, you need to press a series of keys to perform an action:
ctr + k, ctr+d -> reformat code in Visual Studio
Ctrl + m, a -> collapse all foldable code

In option for performing a keystroke there should be something like "Advanced Mode", which lets you input more complex series of keystrokes. It could use the same format as for example Autohotkey app
