* src/frontends/LyXKeySym.h: * src/frontends/qt4/QLyXKeySym.h: * src/frontends/qt4/QLyXKeySym.C (print): add a forgui boolean that tells whether the string should used localized names and special characters. * src/MenuBackend.C (binding): * src/kbmap.C (print): * src/kbsequence.C (print, printOptions): add forgui parameter. * src/frontends/qt4/QLPopupMenu.C (addBinding): use a non-localaized binding for Qt/Mac (because it needs to be parsed back) and a localized one for the others (so that it looks good). * src/kbmap.C (defkey,printbindings): * src/lyxfunc.C (processKeySym,dispatch,viewStatusMessage): adapt to above changes. * src/kbmap.C (printKey): remove. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@16510 a592a061-630c-0410-9148-cb99ea01b6c8
