Paste text into the box, and click on Start. A star (*) will appear in front of the first capital. Click on Keep or Change (to lower case). The star will move to the next capital, and so on. Capitals following a full stop plus space, or a colon plus space, will be ignored.
If your text contains stars already, this will confuse things! Or you may prefer a different marker character. So you can change the star to something else.
