Last change on this file since 103977 was 103578, checked in by vboxsync, 9 months ago
FE/Qt: UIShortcutPool: macOS no more support CMD+? as the default one help Contents shortcut; Let's use another one like CMD+/ (which is same just with Shift modifier released, because CMD+Shift+? now used for system-wide help Search menu).
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
