Can’t assign keyboard shortcut to Add Markup

I assigned the keyboard shortcut Alt-Ctrl-Shift-H to the command Add Markup. However, this shortcut still appears to not work. Executing it just types a capital H. Thanks!

Unfortunately we can’t support alphanumeric shortcuts with both Ctrl and Alt, as Windows interprets those as an AltGr instead. That’s why you’re just getting the capital letter when typing in English.
