$InactivateExclusions

$InactivateExclusions

is a variable whose value is used to determine which heads Inactivate should ignore.

The pair {h,"Symbol"} indicates that Inactivate should ignore the head h itself but not its contents, whereas the pair {h,"Expression"} indicates that Inactivate should ignore any part of the input with head h.
