HSC options are not set in the insert+v dialog any more, since the move to
quick settings. There is no good way to blend your settings options in if
you are being used by a set of application scripts that you don't want to
modify.
Instead, find those settings in the HSC actions menu, hsc mods f10.

HSC can help here, as it has the very helpful, GetColorAtPoint, script
already built in for you, set to Shortcut key, Alt+Shift+NumPad5.
In addition, Double Clicking this keystroke copies the resultant color to
clipboard, for later pasting into Definitions or scripts etc,
in either integer or RGB format, depending on the HSC selection set in the
JawsKey+V quick verbosity dialog.
oooh, just checking that setting selection here though with hsc 217, and I
can no longer see it in here! I wonder have recent changes to this dialog
removed these HotSpotClicker settings from here. I'll consult on that one.
you know about HotSpotClicker, right?
