Maybe you could pay attention to insert screenshots with the corresponding english key denominations instead of the german ones (as the help system is in English).
This may be confusing for english only users.
See attachment for an example.
I run my system with a German locale, sorry.
Nobody ever complained and you can always see the keyboard shortcuts for your locale and language in the actual menu on your system.
I definitely won't redo the screen shots four times in all four official languages IMatch is shipped in.
