When I type a longer card in the canvas, I have a habit to use command+left or command+right to jump at the start/end of the text line that I’m editing. However, in Canvas, this instead just creates a new card, which is ridiculously annoying when trying to edit the text.
Proposed solution
Add an ability to disable this hotkey in the Hotkeys settings.
So I disabled all community plugins I had installed, restarted Obsidian. It appears this annoying hotkey is gone.
Then I reenabled all of them one by one. I’ve now reenabled all the same plugins I had earlier it appears this hotkey is not coming back for some reason.
Anyway, I rechecked every community plugin installed, I found “Canvas Mindmap” is installed which mentions this as a feature: “* Press Cmd / Ctrl + ←/→/↓/↑ to create floating cards;”
so most likely this was coming from this plugin which I’ll just uninstall.
As a tip for later on, in the newer versions of Obsidian, you can filter out hotkeys in Settings > Hotkeys on the actual hotkey, which should have shown you what your particular hotkey was linked to, and in more particular which plugin/module it came from.
