Is it possible to add "sentry" button?

[Plaid]

Using "sentry" function with S hotkey is quite uncomfortable (well, maybe only for me). When language is non-english it dont work. When caps, scroll or num lock activated it will not work. Also somethimes it refuse to work even when all seems perfect (like at the moment i am writing it). If there is more people who have same problems with this function, adding clickable button will be great.

You can also use the Z key. We don't have room for the sentry button. Otherwise we would have added it.
