With 101 keys on the standard keyboard, that would be about 800 lines of "on key label xxx *" just to prevent this kind of trick, executing in the first milliseconds of the start, which I guess nobody has done yet. And then there's the debugger and intellisense in the command window, which make the suspended exe open for surgery.

ON KEY LABEL F1,F2,F3 ....

, see HELP ON KEY LABEL might limit the number of rows a bit

Yes, there are some combinations that are special keys nowadays - ctrl+shift+esc calls up task manager, shift-f10 is your context-menu-key, alt+esc cycles through your open tasks, ctrl+f6 cycles through windows opened by current task etc etc. You still need to plug them all, because it's enough to forget one.

If you want to play that game, that is.
