I should also add to the discussion about cntl-shift-arrow that cntl-arrow by default switches to a different virtual Desktop. Ever since I've been trying to get used to Textadept's cntl-shift-arrow binding I've been accidentally changing my desktop a lot. As in, I just did it again...

I've got 20 years of muscle memory doing that and I guess that's why I can't get over how Textadept is doing it. All of the following apps select by word using alt-shift-arrow. Just to be complete, I'm listing what they do with cntl-shift-arrow.

I actually want to try to push Textadept to the Mac administrators at my university and if this is changed it will help my cause. I'm actually trying to convince people to stop using Electron apps like Atom and Visual Studio Code... Most Mac people I know will only use BBEdit. But because BBEdit is only on the Mac, the crossplatform Mac people might be enticed by Textadept over Atom and VSCode.

The last version of macOS to contain a 10 is macOS 10.15 (and it was released last fall). The next version (released this fall?) wont have any form of 10 or X that's part of its name or version number. I don't know if this is something you really want to change, but I thought I'd let you know. If you were to change it I'd recommend using macOS. I didn't like the name change myself but some battles can't be won so I gave in.

So shift-opt/alt-arrow will select the word. Textadept doesn't use this shortcut, instead it uses shift-cntl-arrow to select text by word. I've been trying to relearn this but it's the only app that I use that does this and I can see it's not going to happen. Is it possible to remap this behavior? I'm afraid it's part of scintilla and isn't modifiable.
