I use an editor that uses 'CTRL-E' and 'SHIFT-CTRL-E' but it causes the site to change to the Update Page. Any way to disable this on the site?
This sounds like something you could very easily avoid on your end.
The hotkey should only trigger when your browser (and specifically the TVmaze tab) is in focus. Do you mean that for you it triggers even when you're actually using an editor? Which browser are you using?
