Explain the problem as you see it
When we are building "knowledge nodes", we have at least two conceptual routes:
(1) open up the node and add children directly to it, or
(2) link related nodes to the "knowledge node" and leverage the "references" counter / section
(you can also have a mix, where after linking you go and write/curate the node's children)
when navigating through a list of knowledge nodes, it's useful to see the "full marker node" as a way to see there is more content if you expand the node. AND it's useful to see the reference counter as an indicator there is more content in the "reference section". BUT there isn't a keyboard shortcut to quicly expand the reference panel, you have to click the counter (or zoom in on the node).
Why is this a problem for you?
When navigating, keyboard shortcuts become second nature and allow you enter your flow.
Suggest a solution
A Command Line to "expand reference section" equivalent to clicking the reference counter in the node
