GithubCreationTest.java tests the end to end creation of a Pipeline in a GitHub repository. This flow makes use of click operations, such as this one, to do its work. It would be nice to add the option to run through similar flows, but instead of using clicks, use keystrokes instead. E.g., the enter-key-to-submit issue documented in JENKINS-46388.
One way this could be implemented might be via the addition of keystroke methods in GithubCreationPage.java. In this way, the method CompleteCreationFlow() could have another parameter added to it (or be overloaded I guess), and be called specifying "use the keyboard" versus "use mouse clicks.
