Working with topic tables

Topic table is perhaps the most general GUI element in Wandora. Topic table is used to view topic collections such as search results, classes, instances and associations. Topic table contains a set of topic cells each representing single topic. Typically a topic is represented as a base name in the table cell. Topic table allows you to select one or more cells in the table. This feature is extremely powerfull as it enables Wandora user to specify what topics are changed with a tool. Topic table selection is created clicking the cells in table. Selection with multiple topics is carried out with pressing SHIFT or CONTROL key down while clicking the cells. Another method to create topic selections beyond single topic is to drag mouse while mouse button is pressed down.
