just tried it.
Unfortunately it never fires using a german keyboard, where it’s shift-7.
Seems all key related events only trigger for the plain keyboard key.
Other keys, like the “<” key e.g. works well on a german keyboard; I assume it won’t work with an US keyboard.
I’ts needed to simulate a key punch for punched cards (see IBM 1401 let's program, part 1: overview - YouTube ), so it would be nice to have a hassle free and language independent access to all necessary keys…
As a first workaround, I will try something easy memorable, like ALT-S.
