Keyboard interaction..

Hi, just started using the latest version and really like it. I'm used to arrow keys to navigate and enter text.. is it possible to:

after entering a note for a node, to use the keyboard to save and dismiss the Notes modal window?
after using the arrow keys to highlight a node, to then use the keyboard to edit the current node text? A bit like MS Excel's Function Key 2 to edit cell in place
undo a mistake when updating a node text.. if I click into an existing node, and accidentally hit a key.. the I cannot get back to the prior state (e.g. cmd-z, or click away, or escape-key) and have to retype what I think was in there before

These are all minor issues, and I can work around them, but maybe I'm missing something.

TIA

Please fix the annoying bug when mistakenly inserting a text in a node then trying to undo.
