## 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: - `mc/mark-next-like-this`: Adds a cursor and region at the next part of the buffer forwards that matches the current region.
(global-set-key (kbd "C-S-c C-S-c") 'mc/edit-lines) - `mc/mark-next-word-like-this`: Like `mc/mark-next-like-this` but only for whole words.
(global-set-key (kbd "C-S-c C-e") 'mc/edit-ends-of-lines) - `mc/mark-next-symbol-like-this`: Like `mc/mark-next-like-this` but only for whole symbols.
(global-set-key (kbd "C-S-c C-a") 'mc/edit-beginnings-of-lines) - `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 ### Mark many occurrences
commands will add one cursor to each line.
;; Rectangular region mode - `mc/mark-all-like-this`: Marks all parts of the buffer that matches the current region.
(global-set-key (kbd "H-SPC") 'set-rectangular-region-anchor) - `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 ### Special
an exceedingly quick way of adding multiple cursors to multiple lines.
;; Mark more like this - `set-rectangular-region-anchor`: Think of this one as `set-mark` except you're marking a rectangular region.
(global-set-key (kbd "M-æ") 'mc/mark-all-like-this) - `mc/mark-sgml-tag-pair`: Mark the current opening and closing tag.
(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)
Okay, yes, I have a crazy norwegian keyboard. Regardless, these will look at ## Tips and tricks
whatever you've got selected at the moment, and mark more places like that in
the buffer.
If you would like to keep the global bindings clean, and get custom keybindings - 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.
