On the Pipeline page, the keyboard shortcuts do not work consistently. It seems that if the browser focus is on the nav bars on the left (in the new nav views), they do work, but if the focus is on the pipelines portion of the page itself, they do not work. When the page loads, it is in the non-working state - mouse click on the nav bars on the left to put focus there.
Also, there is no keyboard shortcut to navigate to the Pipelines within a Repository. (R - P is taken for Pull Requests (that should have been R-R, perhaps), therefore I suggest L for Line or something like that).
