It is self explanatory. As a lot of apps do
- when I’m editing a note and pressing CMD-Return, Agenda should save the note, end editing and switch into note selection
- when a note is selected (not edited) pressing the same keyboard shortcut should start editing at the end of the note
Now, with this selection mode in place, we should have keyboard shortcuts (something+arrow up/down) to navigate up and down between notes on the timeline.
