|
|
<p>For a full interactive introduction to Helix, refer to the
|
|
<a href="https://github.com/helix-editor/helix/blob/master/runtime/tutor">tutor</a> which
|
|
can be accessed via the command <code>hx --tutor</code> or <code>:tutor</code>.</p>

<h2 id="modes"><a class="header" href="#modes">Modes</a></h2>
|
|
<p>Helix is a modal editor, meaning it has different modes for different tasks. The main modes are:</p>
|
|
<ul>
|
|
<li><a href="./keymap.html#normal-mode">Normal mode</a>: For navigation and editing commands. This is the default mode.</li>
|
|
<li><a href="./keymap.html#insert-mode">Insert mode</a>: For typing text directly into the document. Access by typing <code>i</code> in normal mode.</li>
|
|
<li><a href="./keymap.html#select--extend-mode">Select/extend mode</a>: For making selections and performing operations on them. Access by typing <code>v</code> in normal mode.</li>
|
|
</ul>
|
|
<h2 id="buffers"><a class="header" href="#buffers">Buffers</a></h2>
|
|
<p>Buffers are in-memory representations of files. You can have multiple buffers open at once. Use <a href="./pickers.html">pickers</a> or commands like <code>:buffer-next</code> and <code>:buffer-previous</code> to open buffers or switch between them.</p>
|
|
<h2 id="selection-first-editing"><a class="header" href="#selection-first-editing">Selection-first editing</a></h2>
|
|
<p>Inspired by <a href="http://kakoune.org/">Kakoune</a>, Helix follows the <code>selection → action</code> model. This means that whatever you are going to act on (a word, a paragraph, a line, etc.) is selected first and the action itself (delete, change, yank, etc.) comes second. A cursor is simply a single width selection.</p>
|
|
<h2 id="multiple-selections"><a class="header" href="#multiple-selections">Multiple selections</a></h2>
|
|
<p>Also inspired by Kakoune, multiple selections are a core mode of interaction in Helix. For example, the standard way of replacing multiple instance of a word is to first select all instances (so there is one selection per instance) and then use the change action (<code>c</code>) to edit them all at the same time.</p>
|
|
<h2 id="motions"><a class="header" href="#motions">Motions</a></h2>
|
|
<p>Motions are commands that move the cursor or modify selections. They're used for navigation and text manipulation. Examples include <code>w</code> to move to the next word, or <code>f</code> to find a character. See the <a href="./keymap.html#movement">Movement</a> section of the keymap for more motions.</p>
