How does a keyword work?

The operation of the keywords is necessarily done with its management of the "behavior" of copy/paste.

The following window appears: this window is called "Behavior Rules Management".

We're going to create a new behavior to explain the purpose.
When you import photos, they can have attributes. Using the keywords and more precisely with their behavioral settings, Kitview will automatically arrange your photos.

The first "?" is interactive, so you can choose "Keep" or "Lose". Then you will need to select, using the second "?" the keywords you want to (keep or lose). 

By default, when you drag&drop an image to a keyword, the picture will LOSE all the attributes except keywords "End of treatment", "In progress", "Pre-operative", "Preparation", "Start of treatment" and "time". As you can see, we don't touch the attributes of "Processing Status".

You can create many behavior phrases, but only one can be active.
