This is really a feature request but I am marking this minor severity because I
frequently loose (new) data because of MediaWiki's default behavior.

I know this is not the most efficient keyboard shortcut but I have been using
Alt-E to access the edit menu to perform cut, copy and paste operations for the
last ten years.  I use that key combination without even thinking about it. 
However, only in MediaWiki does this keyboard combination destroy any
modifications I have made so far.  I frequently loose serveral minutes worth of
edits when I press Alt-E.

To resolve this situation, I would like a preference to disable the Alt-e
shortcut to edit the current page.  Other possible corrective actions could be
to disable this keyboard shortcut while the user is editing a page or MediaWiki
could prompt the user to make sure the keyboard conbination was really the
intended action.

Please modify this behavior so I do not keep loosing data.
