Follow-up Comment #15, bug #41337 (project octave):

Now about CTRL key. A solution could be to avoid Qt default behavior which is
swapping CTRL and META(CMD). 
I made a trial, adding the following at the beginning  of
main_window::construct_menu_bar (void) (this is probably not the right

  QMenuBar *menu_bar = menuBar ();
  QCoreApplication::setAttribute (Qt::AA_MacDontSwapCtrlAndMeta, true);

Using this trick I can use ctrl modifier as in mac terminal, but hard coded
shortcuts (like CMD+Z, CMD+C ...) don't work anymore as expected.

Replacing all instances of Qt::ControlModifier by a custom
OctaveControlModifier (which would default to Qt::ControlModifier for all
platforms and Qt::MetaModifier for mac) should do the rest of the job.

Do you think it's a viable approach or should we avoid such platform specific
