Taken on 6 first - cycling through label cloud.

Unfortunately, mousewheel support doesn't extend as far back as jdk1.8 so that's out. Alternative, for general consideration, is the space bar.

Implemented this and put it up at xplus/research/update.jsp

You've got to ensure that the applet's got input focus, then move into a label cloud and hit space.

The visible labels are now "frozen" - they move with their associated nodes, but they remain visible even if they drift away from the cursor.
Each subsequent hit on the space bar moves the highlight through the frozen cloud from top to bottom.
A mouse click acts on the highlighted node (to view or expand it).

The cloud is unfrozen as soon as the mouse is moved.
