Undo and redo

Did a papers add and are unhappy with the result?

papers undo

will revert to the previous version. If repeated, it will jump back and forth between the latest and before-latest version. Unless papers is installed with the --git option, in which case papers undo and papers redo will have essentially infinite memory (doing undos and making a new commit risks losing history, unless you keep track of the commit).

See Git integration for how to enable git-tracking.
