Edit a condition

This window is shown when you're adding or editing a condition.

Choose a condition

Choose the condition in the list on the left hand side of the window.
Conditions are sorted in categories. New conditions and new categories can be added if you're using extensions.

Set up the parameters

When a condition is chosen, its name and a description are displayed on the right, along with the parameters that must be completed for using the condition.
For each parameter, you can click on the button at the right of the parameter field so as to open an editor. For example, if the parameter is an expression, the button will open an expression editor.

You can find a list of some paramaters here.
