Cannot set shortcut to Ctrl-ENTER

I noticed that in the recent versions of HeidiSQL a shortcut Ctrl-ENTER is not accepted in the Shortucts interface if I try to use it to remap my keys. Is there a reason behind the change? I used to Ctrl-ENTER for the query execution and in previous versions of Heidi it worked. Then I changed that to something else and could not restore it back anymore...

I suppose you mean the hotkey editor input in the preferences doesn't accept it. This input was a component from SynEdit before v11.1, and now it's a standard THotKey from Delphi's VCL. I was not aware it accepts a different set of hotkeys, but probably there is a reason for this particular one.

That must be some bug in the VCL. Manually, in the Delphi IDE, I can assign Ctrl-Enter without a problem:
