> Multiple clipboards provide flexibility and power. I will be the first to admit that a great deal of people don’t know about this feature, and it is entirely possible to use a computer without it (look at Windows or the Mac OS). That doesn’t mean that I would enjoy losing it, however. macOS sort of has multiple clipboards, if you squint just right, but they aren't all equally supported. Select "aaa", command-C, then put your cursor at the front of "bbb", control-K. You can paste the former with command-V, and the latter with control-Y (just like Emacs). The kill buffer is just for text, and has basically no API, so third-party programs can't (easily) use it. There's also the search selection (command-E), which is pretty much only usable for moving the selection to the search box. It's another semi-persistent way to save some text, though. The situation reminds me of the 6502 (which has 3 registers, each with specific duties), or the 3 robots of Robot Odyssey.
