Type the abbreviation followed by CTRL-] Space to expand the snippet, thencontinue typing normally.Abbreviations may be triggered by any other non-keyword character (different from CTRL-]),but in that case such character is inserted in the text. Try, for example, <tt>i.</tt> followed by CTRL-]and followed by Enter, to see the difference.

Inside the definition of an abbreviation, you marks may be set marks (see <tt>:h m</tt>), which allows allow you to jump between the differentparts of a snippet with TAB (CTRL-O i) and CTRL-I O (in Normal mode) when after the abbreviation is expanded (see <tt>:h jump-motions</tt>).For example, after typing <tt>ch.- </tt><c-]>, the cursor will be at the title's position. If you press <tt><esc><c-otab></tt> (or<tt><c-o><c-otab></tt> if you want to stay in Insert mode after the jump), you will jump between <tt>\startchapter</tt>and <tt>\stopchapter</tt>. You may use <tt><c-i></tt> (in Normal mode) to jump back, or <tt><c-o></tt> to jumpat the end of the snippet.
