Emacs

as mind map user I like to jot idea with parent, children, sibling hierarchy.

I am not satisfied with the present method of creating the three above as need to do a lot of adjustments ex option+ enter to create a new sibiling then ,Shift+<, or Shift+> to adapt the sibiling as a parent or sub. As I am in a creative process would like a faster way to achieve this.

For long list of sibilings I resolved writing in plain text the list and then shift+V and jjjj to select the list and then i launch toggle-heading, but this does not work if I add myself spaces in the plain text.

Please do you know a fast way to open a parent/children/sibiling node, I see a shortcut could be a solution, but do not know if is a good idea because should combine more commands
