When clicking on the collapsed parts of the breadcrumb (the equivalent of “Calendar - Daily Notes,” “2026,” “September,” or “September 14th, 2026” in the picture), I find that cmd+click (windows: Ctrl+click) always opens in a new tab and Alt+click always does nothing.
Meanwhile, clicking the equivalent of “todo” or the visible parts of the breadcrumb, Ctrl+click and Alt+click both work properly to open a node in a new pane.
So odd.
