Keeping a page folded or a keyboard shortcut

Hi - I’ve been enjoying folding my notes as I go - but when I visit another page and return to the one I was working on, my notes are no longer folded. Is there a way to either to remember the prior folding choice or a keyboard short cut to “fold all” on a page?

It isn’t currently possible to keep a page folded, but you can define an Obsidian hotkey to “fold all headings and lists” or “unfold all headings and lists”
