<ctrl-O> - to open a note.
The fuzzy finder makes this super fast,
if you name your notes in a way you'll remember later (SEO!).
<ctrl-E> - switch between reader and edit mode
(I almost always edit with external editor (Vim) any way,
so I nearly always want the note in reader mode.
In settings, you can make this the default)
<ctrl-shift-v> - (custom binding) open current note in external editor
