This function allows you to remove a single frame from a piping chain. Select the frame to be removed from the chain and then click on this icon. The text will disappear from the frame and flow into the other frames of the piping chain. The frame will still exist, but it will be empty, and no longer joined to others in a piping chain. You may do what you like with the released frame.
If you have selected this function accidentally, or change your
mind after selecting this function, you can put the frame back into
the piping chain by using the Insert frame into piping chain
function (see above).
