|
|
<p>One-way key remapping is temporarily supported via a simple TOML configuration
|
|
file. (More powerful solutions such as rebinding via commands will be
|
|
available in the feature).</p>
|
|
<p>To remap keys, write a <code>config.toml</code> file in your <code>helix</code> configuration
|
|
directory (default <code>~/.config/helix</code> in 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]
|
|
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 = "select_line" # Maps Control-Shift-Escape to select_line
|
|
|
|
[keys.insert]
|
|
A-x = "normal_mode" # Maps Alt-X to enter normal mode
|
|
</code></pre>
|
|
<p>Control, 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>
|
|
<ul>
|
|
<li>Backspace => "backspace"</li>
|
|
<li>Space => "space"</li>
|
|
<li>Return/Enter => "ret"</li>
|
|
<li>< => "lt"</li>
|
|
<li>
|
|
<blockquote>
|
|
<p>=> "gt"</p>
|
|
</blockquote>
|
|
</li>
|
|
<li>
|
|
<ul>
|
|
<li>=> "plus"</li>
|
|
</ul>
|
|
</li>
|
|
<li>
|
|
<ul>
|
|
<li>=> "minus"</li>
|
|
</ul>
|
|
</li>
|
|
<li>; => "semicolon"</li>
|
|
<li>% => "percent"</li>
|
|
<li>Left => "left"</li>
|
|
<li>Right => "right"</li>
|
|
<li>Up => "up"</li>
|
|
<li>Home => "home"</li>
|
|
<li>End => "end"</li>
|
|
<li>Page Up => "pageup"</li>
|
|
<li>Page Down => "pagedown"</li>
|
|
<li>Tab => "tab"</li>
|
|
<li>Back Tab => "backtab"</li>
|
|
<li>Delete => "del"</li>
|
|
<li>Insert => "ins"</li>
|
|
<li>Null => "null"</li>
|
|
<li>Escape => "esc"</li>

</ul>
