There are certainly other options for it - like mousekeys - but this aims to be easily modifiable and hardware driven. You can implement custom keys to control functionality, or you can gather information from other peripherals and insert it directly here - let QMK handle the processing for you.</p><p>To enable Pointing Device, add the following line in your rules.mk and specify one of the driver options below.</p><div class="language-make vp-adaptive-theme"><button title="Copy Code" class="copy"></button><span class="lang">make</span><pre class="shiki shiki-themes github-light github-dark vp-code"><code><span class="line"><span style="--shiki-light:#24292E;--shiki-dark:#E1E4E8;">POINTING_DEVICE_ENABLE = yes</span></span></code></pre></div><h2 id="sensor-drivers" tabindex="-1">Sensor Drivers <a class="header-anchor" href="#sensor-drivers" aria-label="Permalink to &quot;Sensor Drivers&quot;">​</a></h2><p>There are a number of sensors that are supported by default.
