Ahhh - 100 chars, that explains why it *feels* intermittent, particular since I never hit this with older Sigil versions. Please do *significantly* raise this (and ideally stop adding the text immediately to the find history too
).
It is very frequent I just want to be able to select a bunch of html and then edit it down in the search box, particularly when you have the nested multiline spans/divs. For instance a book converted from html that has a navigation section up the top with fwd/back etc links that you want to rip the whole thing out. Using Ctrl+F on the selected text (as with pretty much any other text editor) to seed the search box is by far the fastest way, and doesn't have the awful side-effect of losing whatever you had in your clipboard buffer that the drag of copy/paste does.
