I'm on OSX Big Sur 11.1, using v1.5.14.
I notice that Shift-Option-Left no longer selects the previous word.
Also, Option-Left no longer takes me back a word.
I've checked other editors to see if this some kind of OS or settings related issue and don't see the behavior there, so this seems Joplin-related and new.
I have also scanned the forum and couldn't see this issue (though I may have missed it.)
In any case, I love the app and am a huge fan. If this is something that's going to get fixed, I'm keen to know about it. If it's simply that some kind of keyboard setting change has occurred, I'm ready to learn how to adapt.
Any input on this issue will be gratefully received.
