Please try the context menu of the "Commits" view, not the "Files" view.

Does Eclipse documentation automatically occurs like a tooltip or is it triggered by a shortcut as in IDEA?

Please note that some commit messages in some repositories are indeed whole documents. Having a tooltip cover the whole screen seems not useful for me.

Just start typing the repository name.

The fonts and sizes are defined by the operating system.

The 18.1 preview will start soon.

Have you tried to select both commits in the log - the last commit and the remote commit?

Currently, you have 2 Options:

- create a tiny script that invokes git diff > patch and add this as external tool (https://stackoverflow.com/questions/5159185/create-a-git-patch-from-the-changes-in-the-current-working-directory#15438863)

- stash the changes and create the patch from the stash commits

Will be fixed in 18.1 preview 1.
