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.

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

What if the commit 1 is the one with a preparation change and commit 2 being the final feature's change with the appropriate message (a common situation for us)? Do you really suggest 2 different operations that differ just in the way messages are handled?
