the most powerful and well used features of QMK Firmware is the ability to use layers. For most people, this amounts to a function key that allows for different keys, much like what you would see on a laptop or tablet keyboard.</p><p>For a detailed explanation of how the layer stack works, checkout <a href="./keymap#keymap-and-layers">Keymap Overview</a>.</p><h2 id="switching-and-toggling-layers" tabindex="-1">Switching and Toggling Layers <a class="header-anchor" href="#switching-and-toggling-layers" aria-label="Permalink to &quot;Switching and Toggling Layers {#switching-and-toggling-layers}&quot;">​</a></h2><p>These functions allow you to activate layers in various ways. Note that layers are not generally independent layouts -- multiple layers can be activated at once, and it&#39;s typical for layers to use <code>KC_TRNS</code> to allow keypresses to pass through to lower layers. When using momentary layer switching with MO(), LM(), TT(), or LT(), make sure to leave the key on the above layers transparent or it may not work as intended.</p><ul><li><code>DF(layer)</code> - switches the default layer. The default layer is the always-active base layer that other layers stack on top of. See below for more about the default layer. This might be used to switch from QWERTY to Dvorak layout. (Note that this is a temporary switch that only persists until the keyboard loses power. To modify the default layer in a persistent way requires deeper customization, such as calling the <code>set_single_persistent_default_layer</code> function inside of <a href="./custom_quantum_functions#programming-the-behavior-of-any-keycode">process_record_user</a>.)</li><li><code>MO(layer)</code> - momentarily activates <em>layer</em>. As soon as you let go of the key, the layer is deactivated.</li><li><code>LM(layer, mod)</code> - Momentarily activates <em>layer</em> (like <code>MO</code>), but with modifier(s) <em>mod</em> active. Only supports layers 0-15. The modifiers this keycode accept are prefixed with <code>MOD_</code>, not <code>KC_</code>. These modifiers can be combined using bitwise OR, e.g. <code>LM(_RAISE, MOD_LCTL | MOD_LALT)</code>.</li><li><code>LT(layer, kc)</code> - momentarily activates <em>layer</em> when held, and sends <em>kc</em> when tapped. Only supports layers 0-15.</li><li><code>OSL(layer)</code> - momentarily activates <em>layer</em> until the next key is pressed. See <a href="./one_shot_keys">One Shot Keys</a> for details and additional functionality.</li><li><code>TG(layer)</code> - toggles <em>layer</em>, activating it if it&#39;s inactive and vice versa</li><li><code>TO(layer)</code> - activates <em>layer</em> and de-activates all other layers (except your default layer). This function is special, because instead of just adding/removing one layer to your active layer stack, it will completely replace your current active layers, uniquely allowing you to replace higher layers with a lower one. This is activated on keydown (as soon as the key is pressed).</li><li><code>TT(layer)</code> - Layer Tap-Toggle. If you hold the key down, <em>layer</em> is activated, and then is de-activated when you let go (like <code>MO</code>). If you repeatedly tap it, the layer will be toggled on or off (like <code>TG</code>). It needs 5 taps by default, but you can change this by defining <code>TAPPING_TOGGLE</code> -- for example, <code>#define TAPPING_TOGGLE 2</code> to toggle on just two taps.</li></ul><h3 id="caveats" tabindex="-1">Caveats <a class="header-anchor" href="#caveats" aria-label="Permalink to &quot;Caveats {#caveats}&quot;">​</a></h3><p>Currently, the <code>layer</code> argument of <code>LT()</code> is limited to layers 0-15, and the <code>kc</code> argument to the <a href="./keycodes_basic">Basic Keycode set</a>, meaning you can&#39;t use keycodes like <code>LCTL()</code>, <code>KC_TILD</code>, or anything greater than <code>0xFF</code>. This is because QMK uses 16-bit keycodes, of which 4 bits are used for the function identifier and 4 bits for the layer, leaving only 8 bits for the keycode.</p><p>For a similar reason, the <code>layer</code> argument of <code>LM()</code> is also limited to layers 0-15 and the <code>mod</code> argument must fit within 5 bits. As a consequence, although left and right modifiers are supported by <code>LM()</code>, it is impossible to mix and match left and right modifiers. Specifying at least one right-hand modifier in a combination such as <code>MOD_RALT|MOD_LSFT</code> will convert <em>all</em> the listed modifiers to their right-hand counterpart. So, using the aforementionned mod-mask will actually send <kbd>Right Alt</kbd>+<kbd>Right Shift</kbd>. Make sure to use the <code>MOD_xxx</code> constants over alternative ways of specifying modifiers when defining your layer-mod key.</p><table><thead><tr><th style="text-align:center;"><code>LM(1,KC_LSFT)</code></th><th style="text-align:center;"><code>LM(1,MOD_MASK_SHIFT)</code></th><th style="text-align:center;"><code>LM(1,MOD_BIT(KC_LSFT))</code></th><th style="text-align:center;"><code>LM(1,MOD_LSFT)</code></th></tr></thead><tbody><tr><td style="text-align:center;">❌</td><td style="text-align:center;">❌</td><td style="text-align:center;">❌</td><td style="text-align:center;">✅</td></tr></tbody></table><p>Expanding this would be complicated, at best. Moving to a 32-bit keycode would solve a lot of this, but would double the amount of space that the keymap matrix uses. And it could potentially cause issues, too. If you need to apply modifiers to your tapped keycode, <a href="./features/tap_dance#example-5-using-tap-dance-for-advanced-mod-tap-and-layer-tap-keys">Tap Dance</a> can be used to accomplish this.</p><h2 id="working-with-layers" tabindex="-1">Working with Layers <a class="header-anchor" href="#working-with-layers" aria-label="Permalink to &quot;Working with Layers {#working-with-layers}&quot;">​</a></h2><p>Care must be taken when switching layers, it&#39;s possible to lock yourself into a layer with no way to deactivate that layer (without unplugging your keyboard.) We&#39;ve created some guidelines to help users avoid the most common problems.</p><h3 id="beginners" tabindex="-1">Beginners <a class="header-anchor" href="#beginners" aria-label="Permalink to &quot;Beginners {#beginners}&quot;">​</a></h3><p>If you are just getting started with QMK you will want to keep everything simple. Follow these guidelines when setting up your layers:</p><ul><li>Setup layer 0 as your default, &quot;base&quot; layer. This is your normal typing layer, and could be whatever layout you want (qwerty, dvorak, colemak, etc.). It&#39;s important to set this as the lowest layer since it will typically have most or all of the keyboard&#39;s keys defined, so would block other layers from having any effect if it were above them (i.e., had a higher layer number).</li><li>Arrange your layers in a &quot;tree&quot; layout, with layer 0 as the root. Do not try to enter the same layer from more than one other layer.</li><li>In a layer&#39;s keymap, only reference higher-numbered layers. Because layers are processed from the highest-numbered (topmost) active layer down, modifying the state of lower layers can be tricky and error-prone.</li></ul><h3 id="intermediate-users" tabindex="-1">Intermediate Users <a class="header-anchor" href="#intermediate-users" aria-label="Permalink to &quot;Intermediate Users {#intermediate-users}&quot;">​</a></h3><p>Sometimes you need more than one base layer. For example, if you want to switch between QWERTY and Dvorak, switch between layouts for different countries, or switch your layout for different videogames. Your base layers should always be the lowest numbered layers. When you have multiple base layers you should always treat them as mutually exclusive. When one base layer is on the others are off.</p><h3 id="advanced-users" tabindex="-1">Advanced Users <a class="header-anchor" href="#advanced-users" aria-label="Permalink to &quot;Advanced Users {#advanced-users}&quot;">​</a></h3><p>Once you have a good feel for how layers work and what you can do, you can get more creative. The rules listed in the beginner section will help you be successful by avoiding some of the tricker details but they can be constraining, especially for ultra-compact keyboard users. Understanding how layers work will allow you to use them in more advanced ways.</p><p>Layers stack on top of each other in numerical order. When determining what a keypress does, QMK scans the layers from the top down, stopping when it reaches the first active layer that is not set to <code>KC_TRNS</code>. As a result if you activate a layer that is numerically lower than your current layer, and your current layer (or another layer that is active and higher than your target layer) has something other than <code>KC_TRNS</code>, that is the key that will be sent, not the key on the layer you just activated. This is the cause of most people&#39;s &quot;why doesn&#39;t my layer get switched&quot; problem.</p><p>Sometimes, you might want to switch between layers in a macro or as part of a tap dance routine. <code>layer_on</code> activates a layer, and <code>layer_off</code> deactivates it.
