No action with a shortcut of the form "Alt+..." seems to work in the terminal; no problem in other dock widgets. So I don't think it is related to my patch. Could you file another bug report, please?

Thanks Torsten for the fix.

I noticed that in the terminal, setting "Ctrl+..." shortcuts for Copy action works, while with "Alt+..." selected texts are not copied. I tried with and without the "Disable global shortcut ... " option.
Is it related to your last patch or should I file another bug report

Thanks for the tip. The current version of the patch actually uses Qt::MetaModifier.

Thanks Torsten for taking care of this.
If I may, on Mac the interrupt action should be binded to "Qt::ControlModifier + C", not using the placeholder "ctrl" that points to Qt::MetaModifier.

I am preparing a patch, which adds an extra action for interrupting with fixed shortcut Ctrl-C to the terminal. In the case that Ctrl-C (the default) is used for the copy-action, this new action is disabled and the interrupt is handled by the copy routine.

IMHO, we can not handle the duplicate use Ctrl-C in other actions than copy. This implies that selecting the shortcut Ctrl-C to other actions than copy have to be prevented by the shortcut manager.

Confirmed here. The way this is handled is the terminal widget decides whether to interpret the "copy clipboard" action as a copy to clipboard or to send an interrupt signal to the Octave interpreter. Qt handles the platform differences between what the default key sequence for the "copy clipboard" action should be.

Steps to reproduce: open the preference dialog, change the Main/Edit/Copy shortcut to something else than Ctrl+C, apply, in the command window you cannot interrupt anymore e.g.

pause (20)

A workaround is to leave the main Main/Edit/Copy shortcut unchanged in at least one of the available sets of shortcuts and switch back and forth.

I don't know what will happen on mac platform for which the default shortcut for Copy is not Ctrl+C but CMD(META)+C.
