Viewer::keyPressEvent()'s and MagnifyingGlass::keyPressEvent()'s custom matching of these shortcuts is the same as MainWindowViewer::keyPressEvent()'s before the recent commit "Reader: make 3 keyboard shortcuts work with non-Latin layouts". That commit's message details the issues with the custom code. The Magnifying glass actions are now enabled/disabled when loadedComicActions are enabled/disabled - for the same reason (see the recent "Reader: make 12 keyboard shortcuts work with non-Latin layouts" commit). In addition, Viewer::keyPressEvent() propagated the Magnifying glass shortcuts to MagnifyingGlass only when it was visible. Therefore showing/hiding Magnifying glass also enables/disables these actions. Note that Viewer::showMagnifyingGlass() shows Magnifying glass only if render->hasLoadedComic() returns true, so MainWindowViewer::setMglassActionsEnabled slot can be connected directly to Viewer::magnifyingGlassVisibilityChanged signal without checking this condition again.
