<h1 id="key-remapping"><a class="header" href="#key-remapping">Key remapping</a></h1>
<p>Helix currently supports one-way key remapping through a simple TOML configuration
file. (More powerful solutions such as rebinding via commands will be
available in the future).</p>
<p>To remap keys, create a <code>config.toml</code> file in your <code>helix</code> configuration
directory (default <code>~/.config/helix</code> on Linux systems) with a structure like
this:</p>
<pre><code class="language-toml"># At most one section each of 'keys.normal', 'keys.insert' and 'keys.select'
[keys.normal]
C-s = ":w" # Maps Ctrl-s to the typable command :w which is an alias for :write (save file)
C-o = ":open ~/.config/helix/config.toml" # Maps Ctrl-o to opening of the helix config file
a = "move_char_left" # Maps the 'a' key to the move_char_left command
w = "move_line_up" # Maps the 'w' key move_line_up
"C-S-esc" = "extend_line" # Maps Ctrl-Shift-Escape to extend_line
g = { a = "code_action" } # Maps `ga` to show possible code actions
"ret" = ["open_below", "normal_mode"] # Maps the enter key to open_below then re-enter normal mode
[keys.insert]
"A-x" = "normal_mode" # Maps Alt-X to enter normal mode
j = { k = "normal_mode" } # Maps `jk` to exit insert mode
</code></pre>
<h2 id="minor-modes"><a class="header" href="#minor-modes">Minor modes</a></h2>
<p>Minor modes are accessed by pressing a key (usually from normal mode), giving access to dedicated bindings. Bindings
can be modified or added by nesting definitions.</p>
<pre><code class="language-toml">[keys.insert.j]
k = "normal_mode" # Maps `jk` to exit insert mode
[keys.normal.g]
a = "code_action" # Maps `ga` to show possible code actions
# invert `j` and `k` in view mode
[keys.normal.z]
j = "scroll_up"
k = "scroll_down"
# create a new minor mode bound to `+`
[keys.normal."+"]
m = ":run-shell-command make"
c = ":run-shell-command cargo build"
t = ":run-shell-command cargo test"
</code></pre>
<h2 id="special-keys-and-modifiers"><a class="header" href="#special-keys-and-modifiers">Special keys and modifiers</a></h2>
<p>Ctrl, Shift and Alt modifiers are encoded respectively with the prefixes
<code>C-</code>, <code>S-</code> and <code>A-</code>. Special keys are encoded as follows:</p>
<div class="table-wrapper"><table><thead><tr><th>Key name</th><th>Representation</th></tr></thead><tbody>
<tr><td>Backspace</td><td><code>"backspace"</code></td></tr>
<tr><td>Space</td><td><code>"space"</code></td></tr>
<tr><td>Return/Enter</td><td><code>"ret"</code></td></tr>
<tr><td>-</td><td><code>"minus"</code></td></tr>
<tr><td>Left</td><td><code>"left"</code></td></tr>
<tr><td>Right</td><td><code>"right"</code></td></tr>
<tr><td>Up</td><td><code>"up"</code></td></tr>
<tr><td>Down</td><td><code>"down"</code></td></tr>
<tr><td>Home</td><td><code>"home"</code></td></tr>
<tr><td>End</td><td><code>"end"</code></td></tr>
<tr><td>Page Up</td><td><code>"pageup"</code></td></tr>
<tr><td>Page Down</td><td><code>"pagedown"</code></td></tr>
<tr><td>Tab</td><td><code>"tab"</code></td></tr>
<tr><td>Delete</td><td><code>"del"</code></td></tr>
<tr><td>Insert</td><td><code>"ins"</code></td></tr>
<tr><td>Null</td><td><code>"null"</code></td></tr>
<tr><td>Escape</td><td><code>"esc"</code></td></tr>
</tbody></table>
</div>
<p>Keys can be disabled by binding them to the <code>no_op</code> command.</p>
<p>A list of commands is available in the <a href="https://docs.helix-editor.com/keymap.html">Keymap</a> documentation
and in the source code at <a href="https://github.com/helix-editor/helix/blob/master/helix-term/src/commands.rs"><code>helix-term/src/commands.rs</code></a> at the invocation of <code>static_commands!</code> macro and the <code>TypableCommandList</code>.</p>
