What keyboard shortcuts exist for Notes app is OS X?
The app I use for this is CheatSheet  since some shortcuts come from the system (screen shot, etc..), some come from third party apps, and some are from the app itself.

I count 51 keys active in Notes on my Mac, so I'm not going to list them all. Yours are probably different than mine, since I have third party apps that have services with default keys enabled.

The movement request is best served by Mouse Keys - which came from X11 days and has been chosen/implemented as Apple's accessibility solution for using a number pad instead of the mouse/trackpad for you to navigate to the search field.
