This removed the <!--Test--> and <!--End of Test--> lines, but it doesn't
remove all the lines in between, which I think is his real goal.
The problem with the OP's attempted solution is that * is greedy. So it
will match everything from the first <!--Test--> to the last <!--End of
Test-->, including all the non-test stuff in between.
I would do this using a keyboard macro that searches for <!--Test-->, sets
a mark, searches for <!--End of Test-->, and then kills the region.
