Data filter: 'or' requirement

In the master data and lessons windows there is now a comfortable possibility to filter the displayed data by various criteria via the filter line. What is new is that you can enter an 'OR' requirement for your filter. If you want to filter, e.g. in the window 'Lessons | All lessons' by the lessons of the classes 1a and 1b, hold the <CTRL> key and click on both classes in the combo box. Then press <ENTER>. The diagram below shows the outcome

Tip:

You also have the possibility to filter by, e.g. all 1 and 2 period lessons; enter '1|2' in the filter line in the field 'Per'.
