Using VSCode, how do I compare two non-consecutive commits on a file in Gitlens

You can compare two nonconsecutive commits via the following steps (assuming you have the Gitlens extension installed):

• Source Control tab (or Gitlens tab) -> Open the Branches menu.
• From the branches menu -> Open the branch of interest.
• Right click on a particular commit and select “Select for Compare”
• Similarly, find the other commit you’re interested in, right click and select “Compare with Selected”

You will see that under the “Search & Compare” menu, your two different commits are compared.

edit note: you might not see a Gitlens tab anymore as it was (optionally) merged with the Source Control tab, in version 11.2.1.
