Multiple cursors for Emacs. This is some pretty crazy functionality, so yes,
there are kinks. Don't be afraid though, I've been using it since 2011 with
there are kinks. Don't be afraid tho, I've been using it since 2011 with
great success and much merriment.
## Maintenance warning
I use this package every day, and have been doing so for years. It just works.
At least, it works for all my use cases. And if it breaks somehow, I fix it.
However, it has become painfully clear to me that I don't have time to fix
problems I don't have. It's been years since I could keep pace with the issues
and pull requests. Whenever I try, I keep getting feedback that my fix isn't
good enough by some standard I don't particularly care about.
So, I have closed the issue tracker and the pull requests. I hope you can
happily use this package, just like I do. If it doesn't work for you, then I'm
sorry. Thankfully Emacs is infinitely malleable, you can probably fix it
yourself.
TLDR: *I am still maintaining this package*, but I am no longer crowdsourcing a list of issues.
## Installation
I highly recommend installing multiple-cursors through `package.el`.
It's available on [MELPA](http://melpa.org/), [MELPA Stable](http://stable.melpa.org) and
[NonGNU ELPA](https://elpa.nongnu.org/nongnu/multiple-cursors.html) (enabled by default
from Emacs 28 onwards):
M-x package-install multiple-cursors
The package depends on the `cl-lib` package, so if you do not use
`package.el` or have a recent Emacs, you would need to install that
too: see [GNU ELPA](http://elpa.gnu.org/packages/cl-lib.html).

first disable multiple regions before disabling multiple cursors. If you want to
insert a newline in multiple-cursors-mode, use `C-j`.
- `(define-key mc/keymap (kbd "<return>") nil)` will make `<return>` insert a
newline; multiple-cursors-mode can still be disabled with `C-g`.
- Sometimes you end up with cursors outside of your view. You can
scroll the screen to center on each cursor with `C-v` and `M-v` or you can
press `C-'` to hide all lines without a cursor, press `C-'` again to unhide.
scroll the screen to center on each cursor with `C-v` and `M-v`.
- Try pressing `mc/mark-next-like-this` with no region selected. It
will just add a cursor on the next line.
- Try pressing `mc/mark-next-like-this-word` or
`mc/mark-next-like-this-symbol` with no region selected. It will
mark the word or symbol and add a cursor at the next occurrence
- Try pressing `mc/mark-all-like-this-dwim` on a tagname in html-mode.
- Notice that the number of cursors active can be seen in the modeline.

- You can use `mc/reverse-regions` with nothing selected and just one cursor.
It will then flip the sexp at point and the one below it.
- When you use `mc/edit-lines`, you can give it a positive or negative
prefix to change how it behaves on too short lines.
- If you would like to keep the global bindings clean, and get custom keybindings
when the region is active, you can try [region-bindings-mode](https://github.com/fgallina/region-bindings-mode).
- There is a special hook that is run when the mode is diabled
(which is equivalent to the number of cursors going back to 1):
`multiple-cursors-mode-disabled-hook`
BTW, I highly recommend adding `mc/mark-next-like-this` to a key binding that's
right next to the key for `er/expand-region`.

NB! Make sure to do so before requiring multiple-cursors.
It is possible to set multiple-cursors to "run-for-all" for every
command except for those that are listed in `mc/cmds-to-run-once`. To
enable this set `mc/always-run-for-all` to non-nil. Add commands to be
run once to `mc/cmds-to-run-once` in ".mc-lists.el".
## Known limitations
* isearch-forward and isearch-backward aren't supported with multiple cursors.
If you want this functionality, you can use [phi-search](https://github.com/zk-phi/phi-search).
You should feel free to add a simplified version that can work with it.
* Commands run with `M-x` won't be repeated for all cursors.
* All key bindings that refer to lambdas are always run for all cursors. If you
need to limit it, you will have to give it a name.
* Redo might screw with your cursors. Undo works very well.
