[Feature]: Shortcut key to toggle Read-only

[robot-dot-win]

Summary / problem statement

When I'm editing one file, I usually open several other files for reference. I hope to set all reference files to read-only mode in case of modifying them by mistake, so if there's a shortcut key it would be very convenient.

Thanks :)
