BTW, during some of the testing for this, I got into weird situations (one mentioned above) where definitely the In selection checkbox was “out of sync” with how Notepad++ normally handles it.
As another example, I had selected text, and the In selection checkbox was not ticked, but when I did a Find All in Current Document, the Find result window said:
(0 hits in 0 selections of 1 searched)
instead of:
(0 hits in 0 files of 1 searched)
So something funky is up with that.
I remember a recent poster in another thread had said that even though he had selected-text, the In selection box would not “enable” for him so that he could tick it. I tend to take that poster a whole lot more seriously now. :-)
