note create, note delete, toggle view, focus search keybinds

[ButteryCrumpet]

On Mac - ctrl = cmd and alt = opt

Added keybinds:

• ctrl + p -> focus search input
• ctrl + enter -> new note
• ctrl + shift + backspace -> trash note
• ctrl + alt + e -> editor view
• ctrl + alt + s -> split view
• ctrl + alt + p -> preview view

Moved NoteList navigation keybinds to global hook

• alt + arrow up Navigate up
• alt + arrow down Navigate down

I think we should keep these consistent with the keyboard shortcuts from Boostnote.
