  p 'I' "Toggle Invert mode for the current IP. When Invert mode is active, cells are pushed on the stack onto the bottom instead of the top."

  p 'S' "Toggle Switch mode. In Switch mode, the pairs of instructions '[' and ']', '{' and '}', and '(' and ')' are treated as switches. When one is executed, the cell it is located in is immediately overwritten with the other instruction of the pair, providing a switching mechanism and a way to seperate coincident IPs."
