This displays a list of Tinderbox menu matching to the typed term. When a value is typed in the search box the matches are shown beneath it, replacing existing Help menu items. Clear the search box to re-show default menu items.
Hover the mouse over any of the listed matches and Tinderbox will display that (menu) item; a floating blue arrow points to the specific menu item.
Click a listed item and, if the menu item is active, that action is applied.
