Wow, that does sound hairy. I've never wanted anything but to go to the previous change (a command I'm off to implement now using `buffer-undo-list'), so I expect less frustration. I also really like your idea of "hotkeys" for a few register positions -- I love registers and use them as much as I can, but the keybindings do feel cumbersome. > I've also tried the non-chronological approach - visit changes in > position order - but I also didn't like it. > > When I'm looking for older changes, I use Magit Wip mode with Ediff, to > display the changes of the last n minutes.
