| 11 * | |
| 12 * There are two ways to move the cursor: | |
| 13 * 1. Move the cursor directly, the text is scrolled to keep the cursor in the | |
| 14 * window. | |
| 15 * 2. Scroll the text, the cursor is moved into the text visible in the | |
| 16 * window. | |
| 17 * The 'scrolloff' option makes this a bit complicated. | |
