Summary

Coder keyboard shortcuts don't work by default. This is a known issue and there is a workaround. We should mention this very common issue and link to https://coder.com/docs/code-server/latest/FAQ#how-do-i-make-my-keyboard-shortcuts-work in the docs.

Steps to Resolve this Issue

See above.

We might also want to point people in the right direction for non standard keyboards since browsers do not have access to hardware keyboard layouts in a cross platform way there is an extra step needed.

I've also found exporting/importing profiles to be useful - https://code.visualstudio.com/docs/editor/profiles#_export for setting up keyboard settings but also plugins, shortcuts, etc.
