For selecting more than one character state at the same time, press the <CTRL> button plus the respective character states.
(To finalize the query for a selected character, click the <Select> or <Add> menu button and then persue the identification process with another character.)
- bottom left – Query criteria panel: display of previous character state selections.
It is possible to deselect a previous choice by selecting it and subsequently pressing the <Remove Selection> button.
- bottom right – Matching items panel: display of matching items (selecting any item will bring up a complete description of that item).
