+## TUI: toggle to last symbol keybind
+
+Add a single-key toggle that flips between the current symbol and the
+previously selected one (like `cd -` in bash or `Ctrl+^` in vim). Store
+`last_symbol` on `App`; on symbol change, stash the previous. The toggle
+key swaps current and last. Works on any tab — particularly useful for
