- ttttiiiieeee requires a button _b and two valuators _v_1 and _v_2. When a queued
- button changes state, three entries are made in the queue: one records
- the current state of the button and two record the current positions of
- each valuator. The valuators _v_1 and _v_2 need not be (and probably should
- not be) queued.
-
- You can tie one valuator to a button by calling ttttiiiieeee with _v_2 set to
- NULLDEV. You can untie a button by calling ttttiiiieeee with both _v_1 and _v_2 set
- to NULLDEV. _v_1 appears before _v_2 in the event queue; _b precedes both _v_1
- and _v_2.
