The Tabs

This dialog consists of a series of tabs, each containing different elements to be edited.

You will find an "Insert" button on each of these tabs with which you can add the selected element to the editing line. A double-click on the relevant element has the same effect. In addition, you can also add the elements to the editing line with Drag & Drop (also in and from the function list).

For the different elements of an expression (variables, text, functions etc.), certain rules apply for the way of writing and for joining individual elements to give an expression. A wizard integrated in the dialog makes sure that these rules are observed. For this reason, you should always add the different elements to the editing line by means of the respective tab in this dialog. Thus, you should use the "Variables and Functions" tab to enter variables and the "Text" tab to enter text etc.

Experienced users can also enter the expression that they want directly in the edit box or modify the text that is there (e.g. put something in brackets).
