Create multiple cursors to edit in parallel multiple lines of text in the current buffer.
Multiple cursors is especially useful where lines are not entirely identical, i.e. they have the same basic form but have different values
Multiple cursors allows you to call all Emacs named functions and have the results output to each cursor you have created.
iedit or multiple cursors
iedit is excellent for all kinds of search and replace actions where the text to change is the same. iedit finds all matches in a buffer or the scope created by narrowing.
Where text lines do not match but have a similar form, multiple cursors allow for more irregular changes
g r shows the menu for multiple cursors
g r j adds a cursor to the next line
24 g r j will create multiple cursors for 24 consecutive lines.
g r I adds cursors to visual selection lines,
S-v and arrow keys, or
v 20 j to select the next 24 lines
Using Narrowing to constrain where cursors are created
SPC n menu allows you to narrow the view on the current buffer
SPC n f narrows to the current function definition
SPC n r narrows to a selected range of text
See the section on Spacemacs - Narrowing

- Only named commands can be executed by multiple cursors.
- There could be a performance penalty when there are too many cursors (30+).
- Paste will not work when the Spacemacs paste transient state is enabled. This is due to the fact that evil-paste-pop and evil-paste-pop-next commands are not supported.
- evil-repeat works only for some commands. In particular it doesn’t work for delete. It will also interfere with the cursor positions during an undo or redo operation.

- evil-multiedit - used in Doom Emacs
