The air button is an "English-sized" button, instead of the "Anglo-sized" buttons used for the notes, which makes it a smaller target to spot!

The Beaumont's air button is in the same position as the Wheatstone Hayden's -- on the right handrest.

Early in my anglo playing, I "solved" this problem on my 30-button Wheatstone-layout by dropping the D# on button 4a-draw to a D natural. (I say "solved" because of course this solution creates other problems down the road. But at the time, I really wanted that D natural on the draw for precisely the reasons discussed here and didn't yet have tunes in my repertoire which might use the D#.) I've since solved the problem another way, by just switching to the Jeffries-layout Of course, now my playing has advanced to where I periodically want that D#, which is lacking on the 30-button Jeffri
