| Mouse pointer hover
|| Hover over a track/station element to see the mnemonics defined for the item under the mouse pointer. For instance, hovering the mouse over a signal will pop-up a tool-tip that may read something like "P:1EG/1NW".
| Left click, track element
|| Clear (or possibly set) the indication for the clicked item. For instance, clicking on an occupied (red) block will clear the block back to white. Clicking on a signal will toggle it's state between Proceed and Stop. This functionality is provided to clear out "junk" that may accumulate on the dispatchers display from MCPs that are slightly out of range, etc. Note that NOTHING is sent to field devices when doing this, that's technically impossible.
