Windows Paint Shop Pro 9 - Replacing colour?

Well, I've read the help, but after spending ages trying, I can't seem to get this tool working.

I used to have Paint Shop Pro 4, which I could work, but can't figure this out.

Anyone know how to use this tool?

 

It is fairly straightforward.

Using the dropper (or hold down Ctrl while using the Replacer) left-click the original colour (and right-click the desired colour if not already the background colour).
Set the tolerance as required.
Then double right-click to change it all or right-drag over the parts to be changed.

Not sure that makes perfect sense, but if you're stuck just ask.

 

Thanks, finally got it.

 

Wow! Never knew about the double right-click thingy.
Something new learnt today!

 

in case nobody realised, you can also change the colours in the other direction, including the change all.
