What is the function of the "R" button, located to the right of each operation heading?
Example: Numbering (10)-----------[ ]R
I can't find it in Help . . . it's probably there, but I can't find it. Clicking on the checkbox (to left of the "R") toggles it (the check) on/off --- but for what purpose? Clicking on the "R" causes the box to be checked (if it is unchecked), but I can't determine anything else. If unchecked means the operation is turned off, why not just leave it blank? And why is the "R" button needed when the box itself can be clicked?
