This is quite unfortunate. Is there any other option besides changing our internal shortcut that is worth exploring? I can't imagine that we'd want to "disable" window tiling by intercepting these shortcuts before they are sent to the native menu system.

FWIW I can't think of any options other than changing our shortcut which is unfortunate. Do you know if other browsers have this same shortcut?

Mossop, do you think we have other options here?

The default shortcuts for Chrome and Safari are Ctrl+Tab and Shift+Ctrl+Tab. Since these are identical, it might be worth matching these shortcuts.

We already support these shortcuts.

Adding one aspect here that isn't mentioned yet: shortcuts to move tabs left or right are also not working anymore on MacOS 15.

Command	Shortcut
Move Tab Left	Ctrl + Shift + Page Up
Move Tab Right	Ctrl + Shift + Page Down

(Markus told me about option-command-left/right as an alternative here)

Comment 9

[Niko Böckerman]

Could Option+Command+Shift+left/right be changed to be shortcuts for "Move Tab Left" and "Move Tab Right" actions?

:dao, could you have a look please?

Purely from an accessibility perspective, control+tab and control+shift+tab are more conventional, so there is a discoverable workaround. I'm triaging this as access s3 because of this, but breaking muscle memory is nasty, so I totally respect the s2 overall here.

That would break those people who were using that shortcut. Maybe Option+Command+Up/Down?

Aside from a relnote, this needs SUMO updates presumably, as those pages would be out of date.
