Currently, "alt+f3" runs the
find_all_under command, which selects all the occurrences of the already highlighted word in a document -- ready to be replaced, if one types in something. I wonder if it is possible to limit the scope of this kind of selection.
The thing I wanted it for, is to be able to replace some word in a part of the document, pretty much like "find & replace + in selection", but with a nice preview (highlighting) of what is going to get altered, and the ability to adjust it. Currently, I'd have to select a block of text with a mouse, hit ctrl+f, type in the word and preview what's got highlighted. Then, if I'm satisfied with the intermediate result, I'd hit ctrl+h, type in the replacement, and the job is done. However, if too much gets highlighted in the first step, I have no way to adjust: ctrl+f just finds the words, but does not select them to make use of ST2 multiple selection feature. If words were actually selected, I'd just add/remove a few selections with a mouse, and then type in my replacement. I'd use ctrl+d, but its direction seems odd sometimes, and requires numerous key-presses.
