Also as a shortcut pressing the right mouse button will display a context menu containing the entries from the edit menu which pertain to the editors.

#### SQL editors

Editors for SQL have another feature which is code completion. If you place the cursor after a '.' character TOra will this the available columns for the table referenced by the name before the '.' character. This will only work for defined views and tables. You can also look up tablenames using the CTRL+T key which will list all tables starting with the same word as you currently have the cursor in. When the completion list is open you can navigate it using Up, Down keys and selecting an entry using Return. You can also remove the list by pressing the Escape key. The completion values are saved in the object cache and can not be used until it is read. If you find this annoying you can disable this in the preferences.
