underscores in translation

[Nikos Charonitakis]

hi
i ve made an update of el.po (greek) and now i m testing it.
i saw that were conflicts in main window underscores and i fix it
but shortcut keys insist not to  work for greek lang.
example:
i change to greek keyboard press alt+the underscored letter for "file" 
(Greek A) but no menu appears...

also while testing i assign by accident(because underscores dont work) 
some keys combinations to menu "file"
how i can return them to original state.
example file->New (Shift+Greek_nu)
