Is there a shortcut way, besides scrolling of course, to navigate to the topmost bullet of the ancestor or bottommost of the descendant ?
Ctrl+Home and Crtl+End?
If you mean relative to where your cursor is, then nothing inbuilt yet, but halfway there.
Checkout this comment and the newly released keyboard shortcut in the same post:
I believe Ctrl+Home is back and will return you to the node at the top of the page from wherever on the page.
Not sure about getting to the bottom. Ctrl+End does not do that. It seems to do about a page at a time.
Yeaa, never noticed that.. always thought it some sort of bug at my end
