## More commands to play around with
## Command overview
I've set up my key-bindings like so:
### Mark one more occurrence
;; From active region to multiple cursors:
(global-set-key (kbd "C-S-c C-S-c") 'mc/edit-lines)
(global-set-key (kbd "C-S-c C-e") 'mc/edit-ends-of-lines)
(global-set-key (kbd "C-S-c C-a") 'mc/edit-beginnings-of-lines)
- `mc/mark-next-like-this`: Adds a cursor and region at the next part of the buffer forwards that matches the current region.
- `mc/mark-next-word-like-this`: Like `mc/mark-next-like-this` but only for whole words.
- `mc/mark-next-symbol-like-this`: Like `mc/mark-next-like-this` but only for whole symbols.
- `mc/mark-previous-like-this`: Adds a cursor and region at the next part of the buffer backwards that matches the current region.
- `mc/mark-previous-word-like-this`: Like `mc/mark-previous-like-this` but only for whole words.
- `mc/mark-previous-symbol-like-this`: Like `mc/mark-previous-like-this` but only for whole symbols.
- `mc/mark-more-like-this-extended`: Use arrow keys to quickly mark/skip next/previous occurances.
When you have an active region that spans multiple lines, the preceeding three
commands will add one cursor to each line.
### Mark many occurrences
;; Rectangular region mode
(global-set-key (kbd "H-SPC") 'set-rectangular-region-anchor)
- `mc/mark-all-like-this`: Marks all parts of the buffer that matches the current region.
- `mc/mark-all-words-like-this`: Like `mc/mark-all-like-this` but only for whole words.
- `mc/mark-all-symbols-like-this`: Like `mc/mark-all-like-this` but only for whole symbols.
- `mc/mark-all-in-region`: Prompts for a string to match in the region, adding cursors to all of them.
- `mc/mark-all-like-this-in-defun`: Marks all parts of the current defun that matches the current region.
- `mc/mark-all-words-like-this-in-defun`: Like `mc/mark-all-like-this-in-defun` but only for whole words.
- `mc/mark-all-symbols-like-this-in-defun`: Like `mc/mark-all-like-this-in-defun` but only for whole symbols.
- `mc/mark-all-like-this-dwim`: Tries to be smart about marking everything you want. Can be pressed multiple times.
Think of this one as `set-mark` except you're marking a rectangular region. It is
an exceedingly quick way of adding multiple cursors to multiple lines.
### Special
;; Mark more like this
(global-set-key (kbd "M-æ") 'mc/mark-all-like-this)
(global-set-key (kbd "C-å") 'mc/mark-previous-like-this)
(global-set-key (kbd "C-æ") 'mc/mark-next-like-this)
(global-set-key (kbd "C-Æ") 'mc/mark-more-like-this-extended)
(global-set-key (kbd "M-å") 'mc/mark-all-in-region)
- `set-rectangular-region-anchor`: Think of this one as `set-mark` except you're marking a rectangular region.
- `mc/mark-sgml-tag-pair`: Mark the current opening and closing tag.
Okay, yes, I have a crazy norwegian keyboard. Regardless, these will look at
whatever you've got selected at the moment, and mark more places like that in
the buffer.
## Tips and tricks
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).
- To get out of multiple-cursors-mode, press `<return>` or `C-g`. The latter will
first disable multiple regions before disabling multiple cursors. If you want to
insert a newline in multiple-cursors-mode, use `C-j`.
- 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`.
- 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-all-like-this-dwim` on a tagname in html-mode.
- Notice that the number of cursors active can be seen in the modeline.
- 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).
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`.
## Scrolling
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`.
## Unknown commands
Multiple-cursors uses two lists of commands to know what to do: the run-once list

;; Multiple cursors for Emacs. This is some pretty crazy functionality, so yes,
;; there are kinks. Don't be afraid tho, I've been using it since 2011 with
;; great success and much merriment.
;;
;; ## Basic usage
;;
;; Start out with:
;;
;; (require 'multiple-cursors)
;;
;; Then you have to set up your keybindings - multiple-cursors doesn't presume to
;; know how you'd like them laid out. Here are some examples:
;; When you have an active region that spans multiple lines, the following will
;; add a cursor to each line:
;;
;; (global-set-key (kbd "C-S-c C-S-c") 'mc/edit-lines)
;;
;; When you want to add multiple cursors not based on continuous lines, but based on
;; keywords in the buffer, use:
;;
;; (global-set-key (kbd "C->") 'mc/mark-next-like-this)
;; (global-set-key (kbd "C-<") 'mc/mark-previous-like-this)
;; (global-set-key (kbd "C-c C-<") 'mc/mark-all-like-this)
;;
;; First mark the word, then add more cursors.
;;
;; To get out of multiple-cursors-mode, press `<return>` or `C-g`. The latter will
;; first disable multiple regions before disabling multiple cursors. If you want to
;; insert a newline in multiple-cursors-mode, use `C-j`.

;;
;;
;; ## Unknown commands
;;
;; Multiple-cursors uses two lists of commands to know what to do: the run-once list
;; and the run-for-all list. It comes with a set of defaults, but it would be beyond silly
;; to try and include all the known Emacs commands.
;;
;; So that's why multiple-cursors occasionally asks what to do about a command. It will
;; then remember your choice by saving it in `~/.emacs.d/.mc-lists.el`. You can change
;; the location with:
;;
;; (setq mc/list-file "/my/preferred/file")
;;
;;
;; ## Known limitations
;;
;; * isearch-forward and isearch-backward aren't supported with multiple cursors.
;; 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.
;;
;;
;; ## Contribute
;;
;; Yes, please do. There's a suite of tests, so remember to add tests for your
;; specific feature, or I might break it later.
;;
;; You'll find the repo at:
;;
;; https://github.com/magnars/multiple-cursors.el
;;
;; To fetch the test dependencies:
;;
;; $ cd /path/to/multiple-cursors
;; $ git submodule update --init
;;
;; Run the tests with:
;;
;; $ ./util/ecukes/ecukes --graphical

;; ## Contributors
;; * [Takafumi Arakaki](https://github.com/tkf) made .mc-lists.el diff friendly
;; * [Marco Baringer](https://github.com/segv) contributed looping to mc/cycle and adding cursors without region for mark-more.
;; * [Ivan Andrus](https://github.com/gvol) added showing number of cursors in mode-line
;; * [Fuco](https://github.com/Fuco1) added the first version of `mc/mark-all-like-this-dwim`
;; Thanks!
