It was another time when I was writing a comment on some page and it was deleted, so I had to write it again. When I accidentally press right alt+R (there are some words in my language which have "alt" sign before "r", so sometimes I don't release Alt before pressing R - in normal editors it doesn't cause any problems), reader mode starts, but it often doesn't store my comment. How can I disable this shortcut? If it's impossible, please make it possible or fix the reader mode to prevent it from wasting my time.
