Push to talk becomes an action of the BUTTONS page (vr.button_talk),
on an eighth button there, the free hand's grip (its default): it can
trade places with any other action (the move stick's click, say, so
that a player holding a weapon in both hands can talk).
The free hand's grip as a button is pressed once held 0.15 s, at the
threshold halo_vr_two_hand takes the foregrip at, and not at all while
it holds the weapon's foregrip or the Warthog's wheel: taken in that
time, the press is theirs until the grip opens. Before, the runtime's
grip button (which closes before the foregrip's threshold) could open
the microphone for a frame or two as the hand took the weapon.
