| B588 | OR A | At the left edge? If not, step left; otherwise wrap to the right end. | |
| B589 | JR NZ,name_cursor_left_0 | ||
| B58B | LD A,$1D | A wrap off the left edge lands on the strip's rightmost cell. | |
| B58D | LD HL,ATTR_BASE+$101 | Repaint the wrapped-from cell (the strip's leftmost) to the normal bright-white-on-black attribute. The redraw clears only the new index's neighbors, so without this the far end keeps its old highlight. | |

| name_cursor_left_0 | B594 | DEC A | Step one cell left. |
