Fixing PreTranslateMessage so accelerators are handled properly.
Checkpoint trying to fix keyboard shortcuts.
Fixing keyboard shortcut handling.  Disabled shortcuts in menu items no longer trigger their associated Qt actions and confuse the MFC subsystem.  An example of this problem was handling of the DELete key, which was shortcut to ID_EDIT_DELETE, but only if the FrameEditor is in focus or if the Pattern Editor has focus and has a selection.  Otherwise, the DELete key should be passed to the focus widget as a keypress.
Removing some debug messaging.
