Feature Request: Add shortcut to open Diff view from selected commit

[Jelloeater]

It would be really handy to not have to hit C then D to view the diff of the selected commit.

Maybe have it be a separate hotkey or even something like Shift-D to view the diff?

I took an attempt at this feature over the past couple weeks, and it's a bit more complicated than it would first appear.

While it's trivial to immediately load the "diff" view from the todo list, the return path was more complicated.

I want to get a new release out, since there have been a few bug fixes and changes that would be good to release. But I hope this can be a quick follow up after.
