Replacing

The Replace dialog is a supplement to the Find dialog. All the same rules still apply, but now you can replace the found text with some other text., or nothing if you want to remove it.
The most important change is that the Selection only checkbox now applies to the Replace All operation. Replace All will replace all occurrences of the query with the replacement text. Replace in all opened documents will perform a Replace All operation on all the documents that are currently opened in Notepad++.
