Does the Vetra have, for lack of a better term, a "PAUSE" button on it? Some way to stop broadcasting to all PCs?

Situation I'm imagining is something like I'm happily multiboxing away using a Vetra for keyboard input, and but then I start chatting with a friend in game. Naturally, I don't want those keystrokes to be broadcasts multiple times over. What's the solution to that? (Keyclone solution obviously is the "pause" key -- I'm asking if the Vetra has an analogous hardware function).
