Comment 26 for bug 382626

concerning c#23
Letters should not be framed : button already provides a frame & that makes 2 frames, unless you want to imitate a keyboard key like suggested in c#14
See mockup attached : either show a letter, or a key but not something between

Anyway, since current icon is not so bad, i don't think we should change it unless we find a really great icon.
Changing a not so good nor so bad icon for another not so good nor so bad icon would be a bad idea
