After updating to Safari 18 none of the shortcuts of my extension work. I have tried different combinations but none seem to respond.
My extension is unusable without the ability to use shortcuts so this is an important matter to me.
Extension shortcuts not working in Safari 18
After some more testing, it looks like the only shortcuts that broke are those that involve MacCtrl-Shift-{number}.
It looks like it expects the number to be pressed from the numpad. This has to be a bug since this behavior has changed and there's also no way to press those keys in most macs.
