Mathematical function Soft key
Intersected with
e.g. QC10 = QC1 & QC5
Joined with
e.g. QC25 = QC7 | QC18
Joined without intersection
e.g. QC12 = QC5 ^ QC25
Without
e.g. QC25 = QC1 \ QC2
Opening parenthesis
e.g. QC12 = QC1 * (QC2 + QC3)
Closing parenthesis
e.g. QC12 = QC1 * (QC2 + QC3)
Defining a single contour
e.g. QC12 = QC1
