User interface > Main menu > Menu: Help > Wizards > Input tables
There are tables in several wizards for the input of expressions. The operation of these tables is always the same.
There are four buttons in the tool bar:
Insert a new row
Accept the value of the edited field
Cancel changes in the edited field.
Remove row
Edit-mode
After a new row is inserted into the table, the wizard is put into an editing mode, in which some keyboard inputs have changed function. So the work is simpler in the table. The table is in the edit mode now and you can write directly into the fields. The input can be accepted by the accept-button or by the enter key. By the arrow keys you can navigate in the table then and with Strg+Enter you can append a new row.
The edit mode is left by the accept, cancel or delete button or by pressing the Esc key once. If you would press Esc a second time, the wizard would be closed. Attention: the Enter key also get back it's old meaning, when the edit mode is left: it starts the function of the current control element.
Literal
There is a column in some tables with the heading "literal". If the check box is activated in this column, then the token doesn't need a name and the definition text is taken in literal meaning. That means, the characters which have a Meta-meaning in regular expressions, don't have these here: every letter means itself. A backslash doesn't have to be put in front of the quotation mark and the backslash here as in the case of the definition of literal tokens directly within a production either.
