I read the orgguide.pdf when I read page 11,I have a problem.<div>I set some TODO keywords such as </div><div><div>(setq org-todo-keywords</div><div>&#39;((sequence &quot;TODO(t)&quot; &quot;|&quot; &quot;DONE(d)&quot;)</div>
<div>(sequence &quot;REPORT(r)&quot; &quot;BUG(b)&quot; &quot;KNOWNCAUSE(k)&quot; &quot;|&quot; &quot;FIXED(f)&quot;)</div><div>(sequence &quot;|&quot; &quot;CANCELED(c)&quot;)))</div></div><div><br></div><div>and it works,but I am confused about the following:</div>
<div><div>To define TODO keywords that are valid only in a single file, use the following text</div><div>anywhere in the file.</div><div>#+TODO: TODO(t) | DONE(d)</div><div>#+TODO: REPORT(r) BUG(b) KNOWNCAUSE(k) | FIXED(f)</div>
<div>#+TODO: | CANCELED(c)</div></div><div>but it does not work,can someone help me?</div>
