I decided to punt on the STextKnob and use a TextTrigger instead (hence the other couple of posts regarding TextTriggers). This is what I've ended up with:
HEADM adc 2 2 iSwitchL-out iSwitchL-out Empty Empty 1 menupage-obj ;=0,25,100,0
ISWITCH iSwitchL 4 SelectCounter-out adc-in1 adc-null adc-in1 adc-null ;=575,25,100,0
C_MERGE resetCounter 2 SelectCounter-timeout reset-out ;=425,325,100,0
TEXTTRIGGER texttrigger 4 SelectCounter-out "sel 0" "sel 1" "sel 2" "sel 3" ;=575,300,100,0
C_MERGE incrementCounter 3 resetCounter-out texttrigger-out reset-out ;=425,175,100,0
C_COUNTER SelectCounter incrementCounter-out resetCounter-out 1 3 ;=575,175,100,0
MENUPAGE menupage menupage menupage 2 texttrigger-obj reset-obj ;=900,475,100,0
TRIGGER reset reset reset ;=250,475,100,0
