Search engines that can be used via the address bar. Maps a search
engine name (such as <literal>DEFAULT</literal>, or
<literal>ddg</literal>) to a URL with a <literal>{}</literal>
placeholder. The placeholder will be replaced by the search term, use
<literal>{{</literal> and <literal>}}</literal> for literal
<literal>{/}</literal> signs. The search engine named
<literal>DEFAULT</literal> is used when
<literal>url.auto_search</literal> is turned on and something else than
a URL was entered to be opened. Other search engines can be used by
prepending the search engine name to the search term, for example
<literal>:open google qutebrowser</literal>.

This setting can be used to map keys to other keys. When the key used
as dictionary-key is pressed, the binding for the key used as
dictionary-value is invoked instead. This is useful for global
remappings of keys, for example to map Ctrl-[ to Escape. Note that when
a key is bound (via <literal>bindings.default</literal> or
<literal>bindings.commands</literal>), the mapping is ignored.

description = ''
Key bindings mapping keys to commands in different modes. This setting
is a dictionary containing mode names and dictionaries mapping keys to
commands: <literal>{mode: {key: command}}</literal> If you want to map
a key to another key, check the <literal>keyMappings</literal> setting
instead. For modifiers, you can use either <literal>-</literal> or
<literal>+</literal> as delimiters, and these names:
<itemizedlist>
<listitem><para>
Control: <literal>Control</literal>, <literal>Ctrl</literal>
</para></listitem>
<listitem><para>
Meta: <literal>Meta</literal>, <literal>Windows</literal>,
<literal>Mod4</literal>
</para></listitem>
<listitem><para>
Alt: <literal>Alt</literal>, <literal>Mod1</literal>
</para></listitem>
<listitem><para>
Shift: <literal>Shift</literal>
</para></listitem>
</itemizedlist>
For simple keys (no <literal><></literal>-signs), a capital
letter means the key is pressed with Shift. For special keys (with
<literal><></literal>-signs), you need to explicitly add
<literal>Shift-</literal> to match a key pressed with shift. If you
want a binding to do nothing, bind it to the <literal>nop</literal>
command. If you want a default binding to be passed through to the
website, bind it to null. Note that some commands which are only useful
for bindings (but not used interactively) are hidden from the command
completion. See <literal>:</literal>help for a full list of available
commands. The following modes are available:
<variablelist>
<varlistentry>
<term><literal>normal</literal></term>
<listitem><para>
Default mode, where most commands are invoked.
</para></listitem>
</varlistentry>
<varlistentry>
<term><literal>insert</literal></term>
<listitem><para>
Entered when an input field is focused on a website, or by
pressing i in normal mode. Passes through almost all keypresses
to the website, but has some bindings like
<literal><Ctrl-e></literal> to open an external editor.
Note that single keys can’t be bound in this mode.
</para></listitem>
</varlistentry>
<varlistentry>
<term><literal>hint</literal></term>
<listitem><para>
Entered when f is pressed to select links with the keyboard. Note
that single keys can’t be bound in this mode.
</para></listitem>
</varlistentry>
<varlistentry>
<term><literal>passthrough</literal></term>
<listitem><para>
Similar to insert mode, but passes through all keypresses except
<literal><Escape></literal> to leave the mode. It might be
useful to bind <literal><Escape></literal> to some other
key in this mode if you want to be able to send an Escape key to
the website as well. Note that single keys can’t be bound in this
mode.
</para></listitem>
</varlistentry>
<varlistentry>
<term><literal>command</literal></term>
<listitem><para>
Entered when pressing the : key in order to enter a command. Note
that single keys can’t be bound in this mode.
</para></listitem>
</varlistentry>
<varlistentry>
<term><literal>prompt</literal></term>
<listitem><para>
Entered when there’s a prompt to display, like for download
locations or when invoked from JavaScript.
</para></listitem>
</varlistentry>
<varlistentry>
<term><literal>yesno</literal></term>
<listitem><para>
Entered when there’s a yes/no prompt displayed.
</para></listitem>

<varlistentry>
<term><literal>caret</literal></term>
<listitem><para>
Entered when pressing the v mode, used to select text using the
