  <dt id="option_indentWithTabs"><code>indentWithTabs (boolean)</code></dt>

  <dd>Whether, when indenting, the first N*8 spaces should be

  replaced by N tabs. Default is false.</dd>

  <dt id="option_tabMode"><code>tabMode (string)</code></dt>

  <dd>Determines what happens when the user presses the tab key.

  Must be one of the following:

    <dl>

      <dt><code>"classic" (the default)</code></dt>

      <dd>When nothing is selected, insert a tab. Otherwise,

      behave like the <code>"shift"</code> mode. (When shift is

      held, this behaves like the <code>"indent"</code> mode.)</dd>

      <dt><code>"shift"</code></dt>

      <dd>Indent all selected lines by

      one <a href="#option_indentUnit"><code>indentUnit</code></a>.

      If shift was held while pressing tab, un-indent all selected

      lines one unit.</dd>

      <dt><code>"indent"</code></dt>

      <dd>Indent the line the 'correctly', based on its syntactic

      context. Only works if the

      mode <a href="#indent">supports</a> it.</dd>

      <dt><code>"default"</code></dt>

      <dd>Do not capture tab presses, let the browser apply its

      default behaviour (which usually means it skips to the next

      control).</dd>

    </dl></dd>

  <dt id="option_enterMode"><code>enterMode (string)</code></dt>

  <dd>Determines whether and how new lines are indented when the

  enter key is pressed. The following modes are supported:

    <dl>

      <dt><code>"indent" (the default)</code></dt>

      <dd>Use the mode's indentation rules to give the new line

      the correct indentation.</dd>

      <dt><code>"keep"</code></dt>

      <dd>Indent the line the same as the previous line.</dd>

      <dt><code>"flat"</code></dt>

      <dd>Do not indent the new line.</dd>

    </dl></dd>
