History List

The history list facility within each keyword provides convenient access to the last 8 keywords used. Each keyword combo-box control maintains its own history list which is retained even after CatView has shut down.
The history list can be invoked explicitly by using either the mouse or the keyboard key-combination Ctrl-Shift
Some points to note about the History List are:

Keywords are only added to the history list once they have been used in a search
The list is kept in chronological order so that the most recent word used in a search is the first available in the list.
If a keyword that is already in the list is used again, the older list item will be removed ie. duplicates are prevented.
