You don't need a directed flame.

Likewise. I totally agree. It is how you use it that matters. For delicate heating, hold the back of the cup to the SIDE of the flame, so that the flame barely touches the key. a sort of glancing blow.
My Bunsen burner has quite a wide top, so I have put a metal cap on it, with a hole through it, to reduce the diameter of the flame.
If you are getting soot on the key, from using a yellow flame, it is because you are holding the flame too close. The yellow part of the flame contains unburnt carbon, and just beyond the yellow is actually hotter.
