Navigate to PREV / NEXT Note or task in list by key (or button)

Hello.
Based one's workflow just quickly going BACK and FORTH between notes is ESSENTIAL.

At the moment there is no way to "STEP" through 40 or 50 notes. And when using Ctrl+O as a workaround, the recently opened notes just pile up in that list.

When I migrated to AN the previous tool had 7000+ Notes as simple tree structure, allowing me to jump in anywhere by topic or time, and then go UP or DOWN with the arrow keys.

--
All I am / WE ARE asking (based on other comments and votes) might be as simple as that:

== Allow Navigation between notes in the list by up/dn or left/right KEYS. ==

All else: JUST AWESOME!

Thank you.
Counting on you ..
