Thanks for reporting this. Looks like I got sloppy when adding some keybinding configuration stuff in 0.9. I'll post a fixed 0.10 version soon. Sorry about that!

0.10 is posted here and on CurseForge.

Thank you for the speedy fix! 🥇

For sure! I'm gonna close this issue since it seems to be fixed. Keep the bug reports coming eh?
