Enthusiastic new Marked user here! Using Marked Version 2.6.44 (1067) on Sequoia 15.1 (24B2083), if I manually go to the menu to collapse/expand all the headings in the doc, it works, and clicking on individual headings collapses/expands em, but the lovely-looking cmd+opt+left/right arrow shortcut for collapse/expand all doesnay work! any thoughts? thank you for a most righteous product!!!
