Numbered views to quickly teleport around graph (i.e. marks in vim)

It's common to move back and forth between two nodes, for example the prompt and the image output. Using shift+1 and shift+2 I could save two views on the graph, and then simply hit 1 and 2 to alternate between them. This is like in Age of Empires where selected units or buildings can be saved to quickly teleport around the map and play the game at a much higher level. Using numbers allows up to 10 views to be saved.
