Mathematical function Soft key
cut with
e.g. QC10 = QC1 & QC5
joined with
e.g.
QC25 = QC7 | QC18
joined with, but without cut
e.g.
QC12 = QC5 ^ QC25
without
e.g.
QC25 = QC1 \ QC2
Parenthesis open
e.g.
QC12 = QC1 * (QC2 + QC3)
Parenthesis closed
e.g.
QC12 = QC1 * (QC2 + QC3)
Define single contour
e.g.
QC12 = QC1
