Defining multiple comparisons

The property editor allows defining a condition that combines multiple comparisons. Each comparison is represented as a separate row in the lower portion of the property editor. The radio button in front of each row indicate which of the comparisons is currently synchronized with the upper portion of the property editor; it is called the currently selected comparison.

The dropdown menu to the left of each row (starting with the second row) indicates the logical operator (OR or AND) used to combine the consecutive comparisons. It is also used to add and remove comparison rows.

To add a new comparison:
1. Locate the dropdown menu at the bottom left (in front of an empty row) displaying "----".
2. In that dropdown menu, select the desired logical operator "AND" or "OR" instead; a new comparison row is added.
To remove a previously added comparison:
1. Locate the dropdown menu at the start of the comparison row displaying the logical operator "AND" or "OR".
2. In that dropdown menu, select "----" instead; the comparison row is removed.
You cannot remove the first condition since it does not have a logical operator dropdown menu.
To change the logical operator combining two comparisons:
1. Locate the dropdown menu at the start of the second comparison row displaying the logical operator "AND" or "OR".
2. In that dropdown menu, select the other logical operator instead; be careful NOT to select "----" because that would cause the comparison row to be removed.
