So here's the howto for you folks:
In your EventGhost main directory open then file "\lang\English.py" with your favorite text editor. Search for:
DeleteHotKey = ""
and replace it with
DeleteHotKey = "Del"
Now save the file, close EventGhost, reopen it and you should be done
This should work at least for our german friends, too!
-> funktioniert auch, wenn man die deutsche Sprachdatei verwendet! <-
Have a nice day and happy configuring
