Torches and Mounted Lights
Right-click a clear, dry tile beside a wall. The torch belongs to that free tile and hangs at the adjoining wall edge, with a small bracket. Clicking a wall automatically selects the nearest reachable adjacent non-wall tile; the wall is never replaced. Claims and reach apply.
To place a torch above a bed, workbench, chest, furnace or other interactive furniture, hold Shift and right-click. Ordinary right-click still uses the furniture and preserves its contents.
Hold left mouse on a tile with a torch for about 0.3 seconds to remove just the light. This works with any selected item and does not continue into furniture demolition. A short click attacks, including with a hammer. A full inventory or failed save leaves it in place. A short left-click attacks on release; holding left mouse begins work without an initial attack, including over floors, furniture and lights. Existing pre-update torches remain saved and removable; replace an older torch placed directly on a wall to use the new adjacent-tile mounting.
