Add support for mouse forward backward buttons

Summary Other IDEs use this to jump to the previous document or line. Could be useful for faster editing

Alternatives/Considerations Add keybinding settings for the mouse buttons and allow the user to select an action

After the PR:

• Mouse buttons are still not accepted as inputs / keybinds
• Can not jump to previous line or document as in IDEs like VSCode etc.

The two PRs above should get us pretty close to the experience you were requesting. I am going to take a look at enabling customized keybindings next
