## Customizing Caps Word :id=customizing-caps-word

### Invert on shift :id=invert-on-shift

By default, Caps Word turns off when Shift keys are pressed, considering them as
word-breaking. Alternatively with the `CAPS_WORD_INVERT_ON_SHIFT` option,
pressing the Shift key continues Caps Word and inverts the shift state. This
is convenient for uncapitalizing one or a few letters within a word, for
example with Caps Word on, typing "D, B, Shift+A, Shift+A, S" produces "DBaaS",
or typing "P, D, F, Shift+S" produces "PDFs".

Enable it by adding in config.h

```c
#define CAPS_WORD_INVERT_ON_SHIFT
```

This option works with regular Shift keys `KC_LSFT` and `KC_RSFT`, mod-tap Shift
keys, and one-shot Shift keys. Note that while Caps Word is on, one-shot Shift
keys behave like regular Shift keys, and have effect only while they are held.


### Idle timeout :id=idle-timeout

Caps Word turns off automatically if no keys are pressed for
