feat: keybind to jump between trees

[transmissions11]

Is your feature request related to a problem? Please describe.
We have keybinds to jump between parent, child, and sibling nodes, but none to jump between trees, which I often find myself wishing to do.

Describe the solution you'd like
Add keybinds Command + Shift + Left and Command + Shift + Right to navigate to trees in the respective directions, like how navigation between sibling nodes works.

Describe alternatives you've considered
This is basically a subset of the workspace feature requested in #18. That feature is a bit larger and I think we still need a bit more time to decide if that's the optimal way to go, but this specific sub-feature is very tractable and useful even in isolation.

Could it a possible to jump to nodes by searching like algolia? after node rename feature(just search the node name seems a bit simple)?

yea definitely! ideally we search by both content and title. i'd say this is a separate, non-mutex, request though— feel free to open another issue w/ this suggestion.
