"Caps Word" is +a modern alternative to Caps Lock: + +* Letters are capitalized while active, and Caps Word automatically disables + itself at the end of the word. That is, it stops by default once a space or + any key other than `a`--`z`, `0`--`9`, `-`, `_`, delete, or backspace is + pressed. Caps Word also disables itself if the keyboard is idle for 5 seconds. + This is configurable, see below. + +* To avoid requiring a dedicated key for Caps Word, there is an option + (`BOTH_SHIFTS_TURNS_ON_CAPS_WORD`) to activate Caps Word by simultaneously + pressing both shift keys. See below for other options. + +* The implementation does not use the Caps Lock (`KC_CAPS`) keycode.

You may also need to disable or + reconfigure Command, details below. Then, simultaneously pressing both left + and right shifts turns on Caps Word. This method works with the plain + `KC_LSFT` and `KC_RSFT` keycodes as well as one-shot shifts and Space Cadet + shifts. If your shift keys are mod-taps, hold both shift mod-tap keys until + the tapping term, then release them. + +* **Activate by double tapping Left Shift**: Add `#define + DOUBLE_TAP_SHIFT_TURNS_ON_CAPS_WORD` config.h. Then, double tapping Left Shift + turns on Caps Word. This method works with `KC_LSFT` or one-shot Left Shift + `OSM(MOD_LSFT)`. To count as a double tap, the maximum time in milliseconds + between taps is `TAPPING_TERM`, or if using `TAPPING_TERM_PER_KEY`, the time + returned by `get_tapping_term()` for the shift keycode being tapped. + +* **Custom activation**: You can activate Caps Word from code by calling + `caps_word_on()`. This may be used to activate Caps Word through [a + combo](feature_combo.md) or [tap dance](feature_tap_dance.md) or any means + you like. + +### Troubleshooting: Command :id=troubleshooting-command + +When using `BOTH_SHIFTS_TURNS_ON_CAPS_WORD`, you might see a compile message +**"BOTH_SHIFTS_TURNS_ON_CAPS_WORD and Command should not be enabled at the same +time, since both use the Left Shift + Right Shift key combination."** + +Many keyboards enable the [Command feature](feature_command.md), which by +default is also activated using the Left Shift + Right Shift key combination.
