I don't yet have the autohotkey skills to code this myself, or I would. A bit of background:
I am visually impaired, and use a program called Jaws for Windows to interact with the computer. The more windows I have open,
the more annoying it is to alt-tab through them.
It would be nice, as well as being able to hide certain windows, to be able to assign windows a number so that you could hit, for example,
alt+win+1...alt+win+= (or other hotkeys) to be able to switch to a predefined window that you defined with something like alt+win+shift+number, and if there was no window there, it would beep.
