<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 = &quot;:w&quot; # Maps Ctrl-s to the typable command :w which is an alias for :write (save file)
C-o = &quot;:open ~/.config/helix/config.toml&quot; # Maps Ctrl-o to opening of the helix config file
a = &quot;move_char_left&quot; # Maps the 'a' key to the move_char_left command
w = &quot;move_line_up&quot; # Maps the 'w' key move_line_up
&quot;C-S-esc&quot; = &quot;extend_line&quot; # Maps Ctrl-Shift-Escape to extend_line
g = { a = &quot;code_action&quot; } # Maps `ga` to show possible code actions
&quot;ret&quot; = [&quot;open_below&quot;, &quot;normal_mode&quot;] # Maps the enter key to open_below then re-enter normal mode

[keys.insert]
&quot;A-x&quot; = &quot;normal_mode&quot;     # Maps Alt-X to enter normal mode
j = { k = &quot;normal_mode&quot; } # 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 = &quot;normal_mode&quot; # Maps `jk` to exit insert mode

[keys.normal.g]
a = &quot;code_action&quot; # Maps `ga` to show possible code actions

# invert `j` and `k` in view mode
[keys.normal.z]
j = &quot;scroll_up&quot;
k = &quot;scroll_down&quot;

# create a new minor mode bound to `+`
[keys.normal.&quot;+&quot;]
m = &quot;:run-shell-command make&quot;
c = &quot;:run-shell-command cargo build&quot;
t = &quot;:run-shell-command cargo test&quot;
</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>&quot;backspace&quot;</code></td></tr>
<tr><td>Space</td><td><code>&quot;space&quot;</code></td></tr>
<tr><td>Return/Enter</td><td><code>&quot;ret&quot;</code></td></tr>
<tr><td>-</td><td><code>&quot;minus&quot;</code></td></tr>
<tr><td>Left</td><td><code>&quot;left&quot;</code></td></tr>
<tr><td>Right</td><td><code>&quot;right&quot;</code></td></tr>
<tr><td>Up</td><td><code>&quot;up&quot;</code></td></tr>
<tr><td>Down</td><td><code>&quot;down&quot;</code></td></tr>
<tr><td>Home</td><td><code>&quot;home&quot;</code></td></tr>
<tr><td>End</td><td><code>&quot;end&quot;</code></td></tr>
<tr><td>Page Up</td><td><code>&quot;pageup&quot;</code></td></tr>
<tr><td>Page Down</td><td><code>&quot;pagedown&quot;</code></td></tr>
<tr><td>Tab</td><td><code>&quot;tab&quot;</code></td></tr>
<tr><td>Delete</td><td><code>&quot;del&quot;</code></td></tr>
<tr><td>Insert</td><td><code>&quot;ins&quot;</code></td></tr>
<tr><td>Null</td><td><code>&quot;null&quot;</code></td></tr>
<tr><td>Escape</td><td><code>&quot;esc&quot;</code></td></tr>
</tbody></table>
</div>
<p>Keys can be disabled by binding them to the <code>no_op</code> command.</p>
<p>To remove all default bindings, <code>unbind-default-keys = true</code> can be added to the top level configuration.</p>
<pre><code class="language-toml">unbind-default-keys = true

# Only these normal mode bindings will be used
[keys.normal]
n = &quot;normal_mode&quot;
t = &quot;goto_definition&quot;

# remember to add bindings to return to normal mode
[keys.select]
esc = &quot;normal_mode&quot;
