A word of caution though. The path supplied is one of those dratted shortened thingies. It's been so long since I encountered one of these that I forgot what they are called?. These work okay for many purposes, but are likely to confuse some things. There's probably a simply way of retriving the expanded version from the shortened one, but I haven't looked that up yet.
You don't have to look it up, because I know and now I'm
going to tell you.
Substitute "%L" (case does not matter, but in many
font faces it is maddeningly difficult to tell a lowercase "l" from a numeral "1") for "%1".
There's a strong connection between this node and the one
I created here; this (the top node) basically
explains how to do what I didn't cover over there.
The one item not covered in the top node discussion was
that using Regedit manually is not the best way to do this.
Creating a .REG file by exporting a correctly
done new key as detailed in the instructions given,
and then merging it with the target Registry is the better
way (this is commonly accepted). Only one person has to
get it right, and then it's easy to propagate.
One .REG file can serve as a template for any
number of Perl scripts that one would want to run as
context-click GUI add-ons. Only a few characters of the
keynames and the path to the perl script need to be changed.
