Usage:
/NOHILITE [pattern]
With a pattern argument, /nohilite undefines a macro that is triggered by pattern and has the hilite attribute. Pattern is matched against existing patterns using simple comparison.
With no argument, /nohilite turns off the flag %{hilite}, disabling all display attributes.
The flag %{hilite} defaults to 1 (on).
