When a timetable has been imported or manually entered via the Build Timetable option on the Build & Maintain menu, this screen will list every timetable event (lesson) on a separate line, showing the first teacher, the period number and name, the group, year and room.

Any of these may be edited from this screen.  Becsuse there will be hundreds of entries, the Filter dropdown will prove very useful in displaying a manageable list.

Lessons may also be deleted using the Delete buton on the appropriate row.
