hx_InvertSign

Description

It negates the constant and resets the enum/char flag if it was set. When this command is applied the first time to a negative constant, the output will seemingly stay the same. However, the list of symbolic constants available to the M hotkey changes. For example, if the constant is '-2', then before inverting the sign the symbolic constants corresponding to '-2' are available. After inverting the sign the symbolic constants corresponding to '2' are available.
