Locking periods

When one or more periods have been manually set for a lesson they can be individually locked in the timetable by clicking on <Lock period>. This ensures that these periods will not be moved during optimisation. Locked periods are marked with an asterisk '*' in the timetable period window and in the period details window (see figure).

Deactivate the marking in the timetable period window by unchecking the option 'Label locked periods with a * mark' on the 'Layout 2' tab under <Timetable Settings>.

Note: Lock several periods

Hold the <Ctrl> key to highlight several periods in the timetable. Click on the lock icon and the selected periods are locked.
