Request: Add an option to export and import keybinds

[genjonakasone]

There is a well-known issue where a player cannot join a server and will be stuck in loading screen forever, unless they create a brand new profile and join with it instead. While it is possible to transfer addon options through export-import between profiles, there is none such thing for addon keybinds and depending on the modset it might be a lot of stuff to manually configure. Having an option to export those keybinds to clipboard and then import, just like the addon options, would make the process way less troublesome.
