Navigate between filters and pins using keyboard

[GoogleCodeExporter]

I'd like to have this feature in the program:

Navigate between filters using arrow keys
Navigate between pins on the current filter or filters connected to current pin 
using shift-arrow keys

Keyboard or menu operations can then operate on the current selected filter or 
pin (e.g. delete/properties/shift-f10 for context menu) without requiring mouse 
interaction

The feature is important for me because:

Faster to edit the graph using keyboard

The feature is important for other users because:

Faster to edit the graph using keyboard

direction

I hope the moving of the connection line arrow to the middle of the line isn't 
too radical but if so I'm happy to investigate alternatives.

Being able to distinguish clearly which end of a connection line is selected is 
very useful for navigation. Hoping to add more features which can operate on 
the current pin.

Nice feature. The arrow in the middle is also OK.

Still left to do on this feature:

Scroll the view to keep the new selected pin or filter visible.

Limit the positioning of context menus or property windows to make sure they're 
not shown off screen.

Pin selection and connection line drawing are also a bit scrappy visually. Any 
suggestions?
