title: How to change the way that emacs move over a word?
body: <p>I am a junior emacser . I want to know how to change the way that ·emacs· recognize the words.</p>
  
  <p>For example ,   I am at the end of line : <code>(font-spec :family "Microsoft YaHei" :size 13)))</code> , now <code>M-b</code> to move backward over a word:</p>
  
  <p>(use symbol <code>|</code> to mark the caret postion)</p>
  
  <p><strong>emacs:</strong><code>(font-spec :family "Microsoft YaHei" :size |13)))</code><br>
  <strong>sublime:</strong><code>(font-spec :family "Microsoft YaHei" :size 13|)))</code></p>
  
  <p><code>M-b</code> agian</p>
  
  <p><strong>emacs:</strong><code>(font-spec :family "Microsoft YaHei" :|size 13)))</code><br>
  <strong>sublime:</strong><code>(font-spec :family "Microsoft YaHei" :size |13)))</code></p>
  
  <p><code>M-b</code> several times</p>
  
  <p><strong>emacs:</strong><code>(font-spec :family "Microsoft YaHei" |:size 13)))</code><br>
  <strong>sublime:</strong><code>(font-spec :family "Microsoft YaHei" |:size 13)))</code></p>
  
  <p><code>M-b</code> agian</p>
  
  <p><strong>emacs:</strong><code>(font-spec :family "Microsoft |YaHei" :size 13)))</code><br>
  <strong>sublime:</strong><code>(font-spec :family "Microsoft YaHei|" :size 13)))</code></p>
  
  <p><code>M-b</code> several times</p>
  
  <p><strong>emacs:</strong><code>(font-spec :|family "Microsoft YaHei" :size 13)))</code><br>
  <strong>sublime:</strong><code>(font-spec :|family "Microsoft YaHei" :size 13)))</code></p>
  
  <p><code>M-b</code> agian</p>
  
  <p><strong>emacs:</strong><code>(font-|spec :family "Microsoft YaHei" :size 13)))</code><br>
  <strong>sublime:</strong><code>(font-spec |:family "Microsoft YaHei" :size 13)))</code></p>
  
  <p>The way move over a word of <code>emacs</code> is too stange to adapt it . I prefer the way of <code>sublime</code>. I want to know how to change the way that emacs move over a word.thx</p>
