git log -Sword
git log -Gword

-G by default accepts a regex, while -S accepts a string, but it can be modified to accept regexes using the --pickaxe-regex.
-S finds commits where the number of occurrences of "word" changed, while -G finds commits where "word" appears in the diff.
This means that -S<regex> --pickaxe-regex and -G<regex> do not do exactly the same thing.

First, enable NSColorSimulateHardwareAccent

defaults write -g NSColorSimulateHardwareAccent -bool YES

Then choose a color with NSColorSimulatedHardwareEnclosureNumber with a value between 3 and 8 inclusive.

defaults write -g NSColorSimulatedHardwareEnclosureNumber -int 4
