Selection Filter The Selection Filter (configurable under the Setup menu) allows you to set criteria by which notes will be selected. Checking or unchecking the Selection Filter option under the Switches menu toggles the Selection Filter on or off: if Selection Filter is checked, criteria set in the Selection Filter will be used to select notes; if Selection Filter is not checked, Selection Filter criteria will be ignored. The Selection Filter option will be dim and inaccessible if no region is selected or no criteria has been specified in the Selection Filter dialog box (Setup menu). The selection color changes when the Selection Filter is on.
