The reason why bitwise operators are used is that the modifier state is stored as a single byte in the format (GASC)<sub>R</sub>(GASC)<sub>L</sub>.</p><p>Thus, to give an example, <code>01000010</code> would be the internal representation of LShift+RAlt. For more information on bitwise operators in C, click <a href="https://en.wikipedia.org/wiki/Bitwise_operations_in_C" target="_blank" rel="noreferrer">here</a> to open the Wikipedia page on the topic.</p><p>In practice, this means that you can check whether a given modifier is active with <code>get_mods() & MOD_BIT(KC_<modifier>)</code> (see the <a href="./keycodes_basic#modifiers">list of modifier keycodes</a>) or with <code>get_mods() & MOD_MASK_<modifier></code> if the difference between left and right hand modifiers is not important and you want to match both. Same thing can be done for one-shot modifiers if you replace <code>get_mods()</code> with <code>get_oneshot_mods()</code>.</p><p>To check that <em>only</em> a specific set of mods is active at a time, use a simple equality operator: <code>get_mods() == <mod mask></code>.</p><p>For example, let's say you want to trigger a piece of custom code if one-shot left control and one-shot left shift are on but every other one-shot mods are off. To do so, you can compose the desired mod mask by combining the mod bits for left control and shift with <code>(MOD_BIT(KC_LCTL) | MOD_BIT(KC_LSFT))</code> and then plug it in: <code>get_oneshot_mods() == (MOD_BIT(KC_LCTL) | MOD_BIT(KC_LSFT))</code>. Using <code>MOD_MASK_CS</code> instead for the mod bitmask would have forced you to press four modifier keys (both versions of control and shift) to fulfill the condition.</p><p>The full list of mod masks is as follows:</p><table><thead><tr><th>Mod Mask Name</th><th>Matching Modifiers</th></tr></thead><tbody><tr><td><code>MOD_MASK_CTRL</code></td><td>LCTRL , RCTRL</td></tr><tr><td><code>MOD_MASK_SHIFT</code></td><td>LSHIFT , RSHIFT</td></tr><tr><td><code>MOD_MASK_ALT</code></td><td>LALT , RALT</td></tr><tr><td><code>MOD_MASK_GUI</code></td><td>LGUI , RGUI</td></tr><tr><td><code>MOD_MASK_CS</code></td><td>CTRL , SHIFT</td></tr><tr><td><code>MOD_MASK_CA</code></td><td>(L/R)CTRL , (L/R)ALT</td></tr><tr><td><code>MOD_MASK_CG</code></td><td>(L/R)CTRL , (L/R)GUI</td></tr><tr><td><code>MOD_MASK_SA</code></td><td>(L/R)SHIFT , (L/R)ALT</td></tr><tr><td><code>MOD_MASK_SG</code></td><td>(L/R)SHIFT , (L/R)GUI</td></tr><tr><td><code>MOD_MASK_AG</code></td><td>(L/R)ALT , (L/R)GUI</td></tr><tr><td><code>MOD_MASK_CSA</code></td><td>(L/R)CTRL , (L/R)SHIFT , (L/R)ALT</td></tr><tr><td><code>MOD_MASK_CSG</code></td><td>(L/R)CTRL , (L/R)SHIFT , (L/R)GUI</td></tr><tr><td><code>MOD_MASK_CAG</code></td><td>(L/R)CTRL , (L/R)ALT , (L/R)GUI</td></tr><tr><td><code>MOD_MASK_SAG</code></td><td>(L/R)SHIFT , (L/R)ALT , (L/R)GUI</td></tr><tr><td><code>MOD_MASK_CSAG</code></td><td>(L/R)CTRL , (L/R)SHIFT , (L/R)ALT , (L/R)GUI</td></tr></tbody></table><p>Aside from accessing the currently active modifiers using <code>get_mods()</code>, there exists some other functions you can use to modify the modifier state, where the <code>mods</code> argument refers to the modifiers bitmask.</p><ul><li><code>add_mods(mods)</code>: Enable <code>mods</code> without affecting any other modifiers</li><li><code>register_mods(mods)</code>: Like <code>add_mods</code> but send a keyboard report immediately.</li><li><code>del_mods(mods)</code>: Disable <code>mods</code> without affecting any other modifiers</li><li><code>unregister_mods(mods)</code>: Like <code>del_mods</code> but send a keyboard report immediately.</li><li><code>set_mods(mods)</code>: Overwrite current modifier state with <code>mods</code></li><li><code>clear_mods()</code>: Reset the modifier state by disabling all modifiers</li></ul><p>Similarly, in addition to <code>get_oneshot_mods()</code>, there also exists these functions for one-shot mods:</p><ul><li><code>add_oneshot_mods(mods)</code>: Enable <code>mods</code> without affecting any other one-shot modifiers</li><li><code>del_oneshot_mods(mods)</code>: Disable <code>mods</code> without affecting any other one-shot modifiers</li><li><code>set_oneshot_mods(mods)</code>: Overwrite current one-shot modifier state with <code>mods</code></li><li><code>clear_oneshot_mods()</code>: Reset the one-shot modifier state by disabling all one-shot modifiers</li></ul><h2 id="examples" tabindex="-1">Examples <a class="header-anchor" href="#examples" aria-label="Permalink to "Examples {#examples}""></a></h2><p>The following examples use <a href="./feature_macros#advanced-macro-functions">advanced macro functions</a> which you can read more about in the <a href="./feature_macros">documentation page on macros</a>.</p><h3 id="alt-escape-for-alt-tab" tabindex="-1">Alt + Escape for Alt + Tab <a class="header-anchor" href="#alt-escape-for-alt-tab" aria-label="Permalink to "Alt + Escape for Alt + Tab {#alt-escape-for-alt-tab}""></a></h3><p>Simple example where chording Left Alt with <code>KC_ESC</code> makes it behave like <code>KC_TAB</code> for alt-tabbing between applications.

{#shift-backspace-for-delete}""></a></h3><p>Advanced example where the original behaviour of shift is cancelled when chorded with <code>KC_BSPC</code> and is instead fully replaced by <code>KC_DEL</code>. Two main variables are created to make this work well: <code>mod_state</code> and <code>delkey_registered</code>. The first one stores the modifier state and is used to restore it after registering <code>KC_DEL</code>. The second variable is a boolean variable (true or false) which keeps track of the status of <code>KC_DEL</code> to manage the release of the whole Backspace/Delete key correctly.</p><p>As opposed to the previous example, this doesn't use strict modifier checking. Pressing <code>KC_BSPC</code> while one or two shifts are active is enough to trigger this custom code, regardless of the state of other modifiers. That approach offers some perks: Ctrl+Shift+Backspace lets us delete the next word (Ctrl+Delete) and Ctrl+Alt+Shift+Backspace lets us execute the Ctrl+Alt+Del keyboard shortcut.</p><div
