[tde-users] Kate KTextEditor Incremental Search Plugin

There is a collection of Kate plugins in the tdeaddons package. One of the plugins is called KTextEditor Incremental Search Plugin. I am scratching my head how to use the plugin. The respective plugin Comment shows Also known as "As you type search". If I start typing I simply add text to my document. If I invoke the Find dialog nothing happens unless I press the Find button, just like normal search. The Kate Plugins Handbook does not include the plugins from the tdeaddons package. So -- how to use the plugin? And second, is this information cleverly hidden in a handbook? Thanks. :)
