Right Click Menu
The right click menu is always available as long as the cursor is somewhere in the chart area. The content of this menu is very context sensitive. The reason for the "Focused Context Menus", is to keep the number of options down to a reasonable level, and still be able to deal with all situations. There are basic right-click menus when clicking at a random point, and very focused menus when clicking on a waypoint, a route, a track or an AIS target. If you have just created or deleted a waypoint, or if chart groups are defined, there are further entries added to the basic menu. Below, the basic entries are explained.The more context specific entries are dealt with as the concerned feature is explained.
Available "hotkeys", if any, are shown to the right.
Starting with the left menu for rastercharts.
