# CodeMirror: Search/Replace Demo

<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>

Demonstration of primitive search/replace functionality. The keybindings (which can be overridden by custom keymaps) are:

Ctrl-F / Cmd-F
  Start searching
Ctrl-G / Cmd-G
  Find next
Shift-Ctrl-G / Shift-Cmd-G
  Find previous
Shift-Ctrl-F / Cmd-Option-F
  Replace
Shift-Ctrl-R / Shift-Cmd-Option-F
  Replace all

Searching is enabled by including lib/util/search.js. For good-looking input dialogs, you also want to include lib/util/dialog.js and lib/util/dialog.css.
