Details:

In the terminal octave program and other contexts, control-left-arrow and
control-right-arrow (or alt-left-arrow and alt-right-arrow) move backward and
forward one word on the command line. But this isn't working in the Command
Window.

Editing Octave commands without this is cumbersome.

Affects at least 4.4.1 through default (6.0.0 development).

Looks like https://savannah.gnu.org/bugs/?49703, but it's a different bug with
different causes (the Command Window implementation is different on Mac/Linux
and Windows), so I'm opening a separate bug for this.

It looks like this might be related to both:
a) Qt:ControlModifier and Qt::MetaModifier are swapped on macOS
(https://doc.qt.io/qt-5/qt.html#KeyboardModifier-enum)
b) The default keyboard map for Mac in
libgui/qterminal/libqterminal/unix/ExtendedDefaultTranslatorMac.h doesn't have
mappings for Control-arrows
