Each planner has a set of keys. A key comprises a colour, an optional pattern and a description. A key has two purposes. Firstly, it acts as a template for creating planner bookings and secondly it acts as a colour coding representation for each planner booking shown in the Planner window.
Having selected a key in the Key Window, you can then draw planner bookings into the planner. These bookings will inherit the same colour and description as the key. Every planner booking shows it's description, however, sometimes the planner booking is not long enough, in duration, to display the full description. Instead, the key may be used to colour-match any booking in the planner to find its description. Alternatively, positioning the cursor over the planner booking will display a tool tip showing the planner's full description.
