Keywords
Under "Settings > Display and Use > General > Keywords" you can configure that events with certain words in their title or description are displayed with a different color or a different symbol. It is also possible to hide events that contain certain words.![screenshot](keywords_files/screenshot.png)

You can configure if the word should be searched in the title or the location field and which calendars should be affected. Using the "+" button you can add actions that should be applied to events matching the keyword. The events are not modified, they are only displayed differently.
