If the current location is an instruction belonging to a function, then the graph view is available. You can toggle between the text and graph view using the Space key. You can also switch to proximity view by zooming out to the callgraph using the '-' key.
Use the disassembly editing commands to improve the listing.
Use Shift-<arrows> or Alt-L to drop anchor. If you have a mouse, you can drop the anchor with it too.
A double click of the mouse is equvalent to the <Enter> key.
