| 5 * Do ":help uganda" in Vim to read copying and usage conditions. | |
| 6 * Do ":help credits" in Vim to see a list of people who contributed. | |

| 10 * move.c: Functions for moving the cursor and scrolling text. | |
| 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. | |
