Lots of people, including myself, always tend to accidentally trigger an action, when not meaning to. For example, I have noticed that when descending on an elevator, I somehow trigger the crawl action, and it can be quite annoying at some times. If there could be a way to disable/enable these actions, it would be a lot easier for players to avoid accidentally triggering these actions, and only being able to use them when they need to. I, for myself, rarely use actions, and I think it would be a really nice feature to be able to disable them at times.
