It's often the case that we need two nested listwidgets to break down the
results the way we want. In your example, everything is split by ^, but
then it picks the first item from the resulting list (a1). You could
instead split by space, send the result to an inner loop, and then split by
^ .
But in this case, you could use splitregexp :
{{{ [enlist[a1^a2 b1^b2 c1^c2]splitregexp[\^\w\w]] }}}
a1, b1, c1
