Lost `C-w` (`kill-region`) after an update to 2020.2

[jcsims]

First - thanks so much for keeping this working with newer versions! It's been a lifesaver in moving from Emacs to Intellij/Cursive 🙏

I recently updated to IntelliJ 2020.2, and noticed that kill-region had stopped working for me. I've tried going back to the packaged default keymap, and it's not working there either. Checking my keymap, it's the only action bound to C-w. Any idea what may have changed there, or other things I can check?

I've found this in idea logs:

[doktorstick]

Yup, I have this problem on PyCharm 2020.2 Community Edition, too.

[jcsims]

Downgrading to IntelliJ 2020.1.4 did give me this functionality back for the moment.

[metaturso]

I recently started trying this plugin on PHPStorm/IDEA and found this issue as well, how can I downgrade to an earlier version?

[jcsims]

@metaturso I use JetBrain's Toolbox app, which allows for easy downgrading of installed apps. I updated my comment above to clarify as well - I downgraded IntelliJ itself, not the plugin.

[ufobat]

I am having the same issues on 2020.02. would be awesome if this could be fixed.

[stewSquared]

For what it's worth, on 2021.2.3, C-w/M-w works for me with the packaged default emacs keymap, but not with emacs+ (0.3.900 -- same as OP).

[stewSquared]

Compare default with this plugin:

https://github.com/JetBrains/intellij-community/blob/master/platform/platform-resources/src/keymaps/Emacs.xml#L77

https://github.com/cursive-ide/emacs-plus/blob/06d3ebc32c5c26d2ec733e2f1cef6a5262e1f560/src/main/resources/Keymap_EmacsPlus.xml#L322

One possible fix is to replace Emacs+.KillRegion with EditorKillRegion and remove the currently faulty implementation of KillRegion (then do similarly SaveRegion vs EditorKillRingSave)

Edit: This seems to happen because of conflicting bindings with the default and emacs+. I solved it temporarily in my own settings by removing C-w from kill-region and assigning it to Kill Selected Region, and removing M-w from kill-ring-save and leaving it on `Save to Kill Ring"
