keyboard shortcuts are like the fastest way to do anything on a computer so why you may think that its fiddly I doubt many others will and at the same time the right click context menu is a pretty tried and true method of offering options in basically any well coded program. These are tried and true methods found pretty much everywhere in software so if they aren't good enough for you I really don't know what else to say. I don't see navigating to the details pane and clicking something to be a better solution and that is the only thing you mentioned.
