The corpus query editor is the central part of the TIGERSearch tool. For a description of the query language please see chapter III. The query text editor is quite sophisticated, i.e. its features include query syntax highlighting and copy and paste functionality to exchange query texts with other applications (cf. Edit menu in the context menu). Using the Undo and Redo items you can restore corpus queries that have already been submitted.

If you press a character key, the cursor moves to the first item which begins with the corresponding characters:

If you select an item (by double-clicking or pressing the return key), it is copied into the query text editor. The feature popup window can be enabled / disabled in the Input Help menu of the context menu.
