I'll often use Up/^p/^r(i-reverse-search) to find a previous command and edit it's argument, which is where the tree nature of this tool would come in handy. If I 'type' the first n terms of a command enough times, it might be better to alias that part of the command rather than navigate my history and then edit the rest of the command repeatedly.
