When I run
less on some file, the prompt goes away, and I get the contents of the file on screen. Then when I press q, it goes back to the prompt. I think
less does this by saving the current terminal buffer, opening a new buffer, outputting the file into the new one, then when closed, discarding the new buffer, and restoring the old, but I don't know what this process is called or how it does this.

git diff to use a new buffer instead of printing inline. I've already set
git --paginate diff, but they didn't change anything. And I have a workaround, but it's a bit long:
git diff --color=always | less -R

tput smcup and
tput rmcup are high-level commands to do the same thing, probably using the
