[TxMt] Back and forward for switching files?

The tab metaphor for opened files works fairly well, especially if you make the effort to open related files next to each other. The tabs should shrink smaller imo, but that's a separate issue.

The question I have is -- if you are working on two files that are far apart in the tab bar, is there any shortcut for switching between them? My thought is that the program could maintain a history list of viewed files, and then a key binding could be assigned to navigate back and forward over that history list. Could this be added? (Or does this capability exist somehow?)
