Where in the Git documentation can I find :/

Question

Git has this very useful feature of searching in previous commit messages with ":/" (colon slash) operator and picking up the first one that matches, e.g.:

git show :/"unique part of some previous commit message"
git commit --fixup :/"unique part of some previous commit message"

I've been using it for quite some time, but now I wanted to find it in the Git documentation (in pages like git-show, got-commit, git-log &c.) and couldn't. Anybody can point me in the right direction?

Answer 1

It's in the documentation in gitrevisions.
