3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	12 * There are two ways to move the cursor:
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	13 * 1. Move the cursor directly, the text is scrolled to keep the cursor in the
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	14 * window.
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	15 * 2. Scroll the text, the cursor is moved into the text visible in the
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	16 * window.
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	17 * The 'scrolloff' option makes this a bit complicated.
