19 bytes indexed by CorridorCursor (33683, range 0..18); the cell value under the cursor is mirrored to CursorCellValue ($8395) and is what the action key dispatches on. Cell r is drawn on screen row r+1, columns 22-31 (row 0 holds the view title); a cell value >= 70 is the first row of a two-row label, so the cursor highlight covers two rows (see HighlightMenuRow 34882). The cells' meaning depends on the view: on the orders screen (mode 0) they hold the OrdersMenuTemplate (30197) bytes; in the room view (mode 1) each cell holds a string index for the menu row drawn at that position (ResetActionMenu (32684) loads the skeleton from ActionMenuTemplate (30178); the load image holds a hypersleep- room variant: 73 " Destruct ", 74 " Enter ", 75 "Hypersleep"); in the Indicate Location list (modes 2/3, IndicateLocation (35222)) cells 1-17 hold room ids 0-16 or 17-33, framed by cell 0 = 62 "Other List" (page toggle) and cell 18 = 61 " QUIT ".
