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

<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>

<dd>Determines whether and how new lines are indented when the
enter key is pressed. The following modes are supported:

the correct indentation.</dd>
