I always use ctrl+alt+C as shortcut for the copyright symbol (©), but on this forum this shortcut triggers the submit button in the Quick Reply input-field… Kinda annoying tbh. I’ve send PMs and posted replies even though I was in the middle of my sentence a couple of times 
So I was wondering why this particular shortcut is used for the Quick Reply submit button.

I added a disable shortcut plugin. Let me know if its fixed on your end!
Right alt + C x) is a shorter shortcut.
