Lesson two : focus exploration by selecting

Use the UP and DOWN arrow keys to browse the features. To repeat, press SPACE. Please try each feature in the main iSonic window. You can press Alt + TAB to switch between the help window and the main iSonic window.

Instead of exploring the whole map, we can select a few states that are interesting to us and focus on only exploring those states. To select a state, press the L, key, when that state is the current state. If the state has already been selected, pressing the L, key will unselect the state. To unselect all the states, press Ctrl + L.

To focus on only the selected states, press A. In fact, pressing A, will switch the current interest set between "all states" and "selected states only". When we are focusing on "selected states only", all actions, such as spatial sweep or movements on the map will only involve the selected states. Try to select a few states on the map, then switch to "selected regions only", then use the numerical keypad to explore the map to hear what happens.
