Description of the new feature/enhancement

We should add comments above each major section with the link to our documentation.

Additionally, we should add the following settings to settings.json so people can find them easily:

Settings

• "copyOnSelect": false

Key bindings

• { "command": "find", "keys": "ctrl+shift+f" }
  This would also be bound in defaults.json, but we can explain "unbound"/null in a comment above it.
• { "command": {"action": "splitPane", "split": "auto", "splitMode": "duplicate"}, "keys": "alt+shift+d" }
  This is a common panes use case and it also demonstrates the fact that we have panes and shows how the key bindings are formatted.

Proposed technical implementation details (optional)
