Create a radio button captioned text inside parent.
Pass firstInGroup = true for the first button of a group. That button is
the group's single tab stop (WS_TABSTOP) and starts the group; the
remaining buttons are reached with the arrow keys, not Tab. A non-first
button therefore drops both its tab stop and the WS_GROUP the control base
adds by default, so it continues the previous button's group instead of
starting a new one. End the group by giving the next control WS_GROUP
(every Deft control has it by default, so a following non-radio control
terminates the group automatically).
