I have just discovered for myself the xlib output "language" dot supports. It is actually very nice because of its performance if used e.g. with http://github.com/esc/git-big-picture to visualize hairy and lengthy git development trees.
But its keybindings / mouse shortcuts are quite limited (closer to rudimentary) -- could someone point to the list of supported ones?
I wonder if it is feasible for it to be extended with a callback command which would be ran provided selected node/edge information...?
Thank you in advance!
