this is just great:
ctrl-shift-x in firefox3 right-justifies edit-box text ( and text in your address bar! )
apparently some people do *like* this feature ( makes sending emails in hebrew easier ) but it’s horribly close to “cut” ( ctrl-x ) especially if you are selecting text at the time ( via “shift” ).
even better: this isn’t a documented shortcut and there isn’t ( apparently ) anyway to disable it.
