Creating/Editing a HotSpot
In the HotSpots management dialog you will find a list of the existing Hotspots. You will also find the New icon, which you can use to create a new HotSpot.
If you want to modify the attributes of a previously created HotSpot, select it using the mouse and then select Next, or just simply double-select it.

After you select Next, you will be presented with a dialog in which you will have access to all the attributes of the HotSpot you are creating or editing.
Info
In order to be able to use your Hotspot within a Connection, you must first enable the Hotspot for that particular connection from the Connections Settings dialog.
