+title: Caps Word Behavior
+sidebar_label: Caps Word
+---
+
+## Summary
+
+The caps word behavior behaves similar to a caps lock, but will automatically deactivate when any key not in a continue list is pressed, or if the caps word key is pressed again. For smaller keyboards using [mod-taps](mod-tap.md), this can help avoid repeated alternating holds when typing words in all caps.
+
+The modifiers are applied only to the alphabetic (`A` to `Z`) keycodes, to avoid automatically applying them to numeric values, etc.
+
+### Behavior Binding
+
+- Reference: `&caps_word`
+
+Example:
+
+```dts
+&caps_word
+```
+
+### Configuration
+
+#### Continue list
+
+By default, the caps word will remain active when any alphanumeric character or underscore (`UNDERSCORE`), backspace (`BACKSPACE`), or delete (`DELETE`) characters are pressed. Any other non-modifier keycode sent will turn off caps word. If you would like to override this, you can set a new array of keys in the `continue-list` property in your keymap:
+
+```dts
+&caps_word {
+    continue-list = <UNDERSCORE MINUS>;
+};
+
+/ {
+    keymap {
+        ...
+    };
+};
+```
+
+#### Applied modifier(s)
+
+In addition, if you would like _multiple_ modifiers, instead of just `MOD_LSFT`, you can override the `mods` property:
+
+```dts
+&caps_word {
+    mods = <(MOD_LSFT | MOD_LALT)>;
+};
+
+/ {
+    keymap {
+        ...
+    };
+};
+```
+
+### Multiple Caps Breaks
+
+If you want to use multiple caps breaks with different codes to break the caps, you can add additional caps words instances to use in your keymap:
+
+```dts
+/ {
+    prog_caps: prog_caps {
+        compatible = "zmk,behavior-caps-word";
+        #binding-cells = <0>;
+        continue-list = <UNDERSCORE>;
+    };
+
+    keymap {
+        ...
+    };
+};
+```
