Marking records and using the subset

BookCAT allows you to mark records in any table. Marking and unmarking records can be useful if you want to select different records based on specific criteria. You can view, edit, search among, or print only the records that have been marked.

The checkmark button on the toolbar indicates whether the current record is marked or not. If the button is "in" (pressed), the record is marked. If it is "out" (released), the record is not marked. You can also simply press Ctrl + M to mark or unmark the current record.

You can also mark / unmark records by clicking the checkbox at the far left of the browse list.

To mark all records:

1.	Choose Mark / Mark All from the Book, Contents or Lookup menu. You can also simply press Ctrl + F7. Note: If this command is disabled (not available), it means that all records already are marked.

To unmark all records:

1.	Choose Mark / Unmark All from the Book, Contents or Lookup menu. You can also simply press Ctrl + F8. Note: If this command is disabled (not available), it means that no records are marked.

At the bottom of the main window, notice the first section of the statusbar:

It shows the active record's position in the list (2), number of records displayed in the list (5), number of records that are marked (6), and the total number of records in the table (32).

Notice how the statusbar is updated when you use the mark commands.

By default, BookCAT displays all records in the active table. If you want to view only the records that are marked, the subset, activate the Subset command on the List menu.

1.	Choose Subset from the List menu, or click the Subset button on the toolbar. You can also press F9. This command toggles between the two modes. If the subset was active, it is deactivated. If the subset was not active, it is activated.
