It's almost impossible to review Close Votes from the review queues without a mouse.
For accessibility purposes, it would be much better if the same keyboard shortcuts that you'd use from the question would work in the queue.
Currently, it's very hard to select a close reason. Allowing me to go c, 1, enter (for example) in the queue would be much better than having to fool around with double-right clicking to get the focus in the right place.
If you're confused as to why it's important that things be accessible without the mouse, please read up on keyboard accessibility. While I thankfully don't have any physical problems with using a mouse, I'm using my time with a broken mouse to give accessibility feedback so that people who need it can get a better site experience.
