There is play/pause, +20 and -20 seconds, go to the start of the stream and (for live broadcasts) go to now. The latter is very close to Git's fast-forward, but is not labelled as such. There is also a time-line, where the user can go to an arbitrary point in time and play from there. > Hardware players do have fast-forward controls, even for streams, or files. Yes, but regardless of that for whatever reason it's already part of the culture, and people are using fast-forward irrespective of the original meaning: "They fast-forward to present day ten years later, where he has been hospitalized and is on life support." [1] "So then fast-forward to now and, like, six months ago, they found the script and called me up." [2] This is similar to what happened with the floppy disk icon. New generations may have no idea what it originally meant, regardless of that today it means "save". Except the fast-forward button still exists in many remote controls. Same with other concepts like carbon copy. I'm not sure if newer generations have ever seen an actual physical carbon copy take place. Or a physical bookmark. Words evolve beyond their original meaning, and today I think that has already happened with fast-forward. > So, yes, the term is very widely known in the wider world (even for those who didn't grow up with tape). > And yes, irrespective of the above, it makes complete sense for git's usage.
