Just from the title / tooltip of the actions, it's not clear what's the difference between the two: <img width="378" alt="Screenshot 2019-04-30 at 15 13 24" src="https://user-images.githubusercontent.com/101152/56963976-8559e300-6b5a-11e9-9a12-a66f8eab2fdb.png"> This is what they do: https://github.com/eamodio/vscode-gitlens/blob/5020fe18f0972f060a247976530b6e91fb97099d/src/git/gitService.ts#L1415-L1420 The harder part is how to explain the difference 😄 [This StackOverflow answer](https://stackoverflow.com/a/1340245/21728) is quite nice. In GitLens' UI, it would at least be useful to add this: - or, by changes (`-G`) - or, by changed lines (`-S`) Suggestion for respective tooltips: - "Show commits whose diffs contain the pattern" - "Show commits that add or delete the pattern"
