You can only edit the text fields in the column Value.

To edit numerical values it is possible with the arrow keys or the Page Up/Down keys to change the value by one or ten units respectively. A double click with the mouse also changes the value by increasing by one unit. A typing check is installed for numerical values: <Ctrl> + <Home> or <Ctrl> + <End> deliver the lowest or the highest value respectively for the possible input values for the type of parameter in question.
