For me the nice thing about multiple cursors is when it would take more time to write the regex than it does to just throw down say 8 cursors and update the spots.
There’s an overlap between “Find and Replace” and Macros, but it’s too small for multi cursors to be particularly useful for me. Especially with emacs where I can bring up all the lines in a separate buffer and edit them there (occur-mode) or do the same for a set of files (grep-mode and wgrep)
How do you place the cursors then?
