I use a KEYDOWN routine in my main TFORM to check for the key Ctrl+Q:----------------------------------------------------------------- procedure TForm1.FormKeyDown(Sender : TObject; var Key : Word; Shift : TShiftState); begin // TForm1.FormKeyDown case key of VK_Q : begin if Shift=[ssCtrl] then begin .... ----------------------------------------------------------------- But when I type "Ctrl+Q" then "Key" is 17 instead of VK_Q (81). If I now use 17 to trigger the "Q" key, then it is also triggered when I just type the Ctrl-key (without any other key)! This is all a bit weird. How can I detect that "Ctrl+Q" is pressed without getting fooled by any other key?
Watch out for operating systems which still handle ^S ^Q and possibly ^P specially. I was painfully reminded of this the other day when I hit ^S in an SSH session and everything ground to a halt.
