Okay, shift+end helped me out there, thanks. Just wasn't getting the fold marker for some reason.
Cut/Paste works fine. I don't suppose there's any way to change ST2's behavior to let ctrl+shift+up/down to function as expected, i.e. move the selected head line + folded section up and down among the other folded head lines and their attached folded sections without them passing through the folded content? Barring that, is there any way to change the paste behavior to where it simply pastes as it was copied, i.e. folded, rather than unfolded with caret at the end of the pasted selection?
