Logical/Boolean/True-False fields may optionally be displayed as check boxes in the data grid selected via the Options menu.
If in editable state, the fields may be cycled through True/False or True/False/NULL by clicking the check boxes or by pressing the keyboard space bar.
The optional NULL "value" or state will depend on if the field is Required (NOT NULL), and if not being a required value field, then if you have selected this option via the Options menu. If having the NULL "value" the check box will be grayed.
Whatever displayed as check boxes or as standard True/False text, the stored as well as exported values will always be of the format True/False(/Null), where NULLs are exported as empty field values.
