"M-x" gives Emacs users a command line prompt to type (and tab complete) an Emacs command, and in the above explanation, the user is running the "grep" command of Emacs, which in turn prompts for a shell command that produces series of <filename>:<lineno>:<cruft> to jump around [*]. "M-x grep<RET>git jump --stdout diff<RET>" is what I would have written on the second line instead of "Run grep (like this)...". [Footnote] * People often run "grep -n -r -e <pattern>" but you can run things like "git grep -n -e <pattern> -- <pathspec>" and "find -name \*.h | xargs grep -n -e <pattern>".
