28 ;; This is the CUA package which provides a complete emulation of the
29 ;; standard CUA key bindings (Motif/Windows/Mac GUI) for selecting and
30 ;; manipulating the region where S-<movement> is used to highlight &
33 ;; CUA style key bindings for cut and paste
34 ;; ----------------------------------------
36 ;; This package allows the C-z, C-x, C-c, and C-v keys to be
37 ;; bound appropriately according to the Motif/Windows GUI, i.e.
43 ;; The tricky part is the handling of the C-x and C-c keys which
44 ;; are normally used as prefix keys for most of emacs' built-in
45 ;; commands. With CUA they still do!!!
47 ;; Only when the region is currently active (and highlighted since
48 ;; transient-mark-mode is used), the C-x and C-c keys will work as CUA
52 ;; When the region is not active, C-x and C-c works as prefix keys!
54 ;; This probably sounds strange and difficult to get used to - but
55 ;; based on my own experience and the feedback from many users of
56 ;; this package, it actually works very well and users adapt to it
57 ;; instantly - or at least very quickly. So give it a try!
58 ;; ... and in the few cases where you make a mistake and accidentally
59 ;; delete the region - you just undo the mistake (with C-z).
61 ;; If you really need to perform a command which starts with one of
62 ;; the prefix keys even when the region is active, you have three options:
63 ;; - press the prefix key twice very quickly (within 0.2 seconds),
64 ;; - press the prefix key and the following key within 0.2 seconds), or
65 ;; - use the SHIFT key with the prefix key, i.e. C-X or C-C
67 ;; This behaviour can be customized via the
68 ;; cua-prefix-override-inhibit-delay variable.
70 ;; In addition to using the shifted movement keys, you can also use
71 ;; [C-space] to start the region and use unshifted movement keys to extend
72 ;; it. To cancel the region, use [C-space] or [C-g].
74 ;; If you prefer to use the standard emacs cut, copy, paste, and undo
75 ;; bindings, customize cua-enable-cua-keys to nil.
78 ;; Typing text replaces the region
79 ;; -------------------------------
81 ;; When the region is active, i.e. highlighted, the text in region is
82 ;; replaced by the text you type.
84 ;; The replaced text is saved in register 0 which can be inserted using
85 ;; the key sequence M-0 C-v (see the section on register support below).
87 ;; If you have just replaced a highlighted region with typed text,
88 ;; you can repeat the replace with M-v. This will search forward
89 ;; for a streach of text identical to the previous contents of the
90 ;; region (i.e. the contents of register 0) and replace it with the
91 ;; text you typed to replace the original region. Repeating M-v will
92 ;; replace the next matching region and so on.
94 ;; Example: Suppose you have a line like this
95 ;; The redo operation will redo the last redoable command
96 ;; which you want to change into
97 ;; The repeat operation will repeat the last repeatable command
98 ;; This is done by highlighting the first occurrence of "redo"
99 ;; and type "repeat" M-v M-v.
101 ;; Note: Since CUA-mode duplicates the functionality of the
102 ;; delete-selection-mode, that mode is automatically disabled when
103 ;; CUA-mode is enabled.
106 ;; CUA mode indications
107 ;; --------------------
108 ;; You can choose to let CUA use different cursor colors to indicate
109 ;; overwrite mode and read-only buffers. For example, the following
110 ;; setting will use a RED cursor in normal (insertion) mode in
111 ;; read-write buffers, a YELLOW cursor in overwrite mode in read-write
112 ;; buffers, and a GREEN cursor read-only buffers:
114 ;; (setq cua-normal-cursor-color "red")
115 ;; (setq cua-overwrite-cursor-color "yellow")
116 ;; (setq cua-read-only-cursor-color "green")
119 ;; CUA register support
120 ;; --------------------
121 ;; Emacs' standard register support is also based on a separate set of
122 ;; "register commands".
124 ;; CUA's register support is activated by providing a numeric
125 ;; prefix argument to the C-x, C-c, and C-v commands. For example,
126 ;; to copy the selected region to register 2, enter [M-2 C-c].
127 ;; Or if you have activated the keypad prefix mode, enter [kp-2 C-c].
129 ;; And CUA will copy and paste normal region as well as rectangles
130 ;; into the registers, i.e. you use exactly the same command for both.
132 ;; In addition, the last highlighted text that is deleted (not
133 ;; copied), e.g. by [delete] or by typing text over a highlighted
134 ;; region, is automatically saved in register 0, so you can insert it
137 ;; CUA rectangle support
138 ;; ---------------------
139 ;; Emacs' normal rectangle support is based on interpreting the region
140 ;; between the mark and point as a "virtual rectangle", and using a
141 ;; completely separate set of "rectangle commands" [C-x r ...] on the
142 ;; region to copy, kill, fill a.s.o. the virtual rectangle.
144 ;; cua-mode's superior rectangle support is based on using a true visual
145 ;; representation of the selected rectangle. To start a rectangle, use
146 ;; [S-return] and extend it using the normal movement keys (up, down,
147 ;; left, right, home, end, C-home, C-end). Once the rectangle has the
148 ;; desired size, you can cut or copy it using C-x and C-c (or C-w and M-w),
149 ;; and you can subsequently insert it - as a rectangle - using C-v (or
150 ;; C-y). So the only new command you need to know to work with
151 ;; cua-mode rectangles is S-return!
153 ;; Normally, when you paste a rectangle using C-v (C-y), each line of
154 ;; the rectangle is inserted into the existing lines in the buffer.
155 ;; If overwrite-mode is active when you paste a rectangle, it is
156 ;; inserted as normal (multi-line) text.
158 ;; Furthermore, cua-mode's rectangles are not limited to the actual
159 ;; contents of the buffer, so if the cursor is currently at the end of a
160 ;; short line, you can still extend the rectangle to include more columns
161 ;; of longer lines in the same rectangle. Sounds strange? Try it!
163 ;; You can enable padding for just this rectangle by pressing [M-p];
164 ;; this works like entering `picture-mode' where the tabs and spaces
165 ;; are automatically converted/inserted to make the rectangle truly
166 ;; rectangular. Or you can do it for all rectangles by setting the
167 ;; `cua-auto-expand-rectangles' variable.
169 ;; And there's more: If you want to extend or reduce the size of the
170 ;; rectangle in one of the other corners of the rectangle, just use
171 ;; [return] to move the cursor to the "next" corner. Or you can use
172 ;; the [M-up], [M-down], [M-left], and [M-right] keys to move the
173 ;; entire rectangle overlay (but not the contents) in the given
176 ;; [S-return] cancels the rectangle
177 ;; [C-space] activates the region bounded by the rectangle
179 ;; If you type a normal (self-inserting) character when the rectangle is
180 ;; active, the character is inserted on the "current side" of every line
181 ;; of the rectangle. The "current side" is the side on which the cursor
182 ;; is currently located. If the rectangle is only 1 column wide,
183 ;; insertion will be performed to the left when the cursor is at the
184 ;; bottom of the rectangle. So, for example, to comment out an entire
185 ;; paragraph like this one, just place the cursor on the first character
186 ;; of the first line, and enter the following:
187 ;; S-return M-} ; ; <space> S-return
189 ;; cua-mode's rectangle support also includes all the normal rectangle
190 ;; functions with easy access:
192 ;; [M-a] aligns all words at the left edge of the rectangle
193 ;; [M-b] fills the rectangle with blanks (tabs and spaces)
194 ;; [M-c] closes the rectangle by removing all blanks at the left edge
196 ;; [M-f] fills the rectangle with a single character (prompt)
197 ;; [M-i] increases the first number found on each line of the rectangle
198 ;; by the amount given by the numeric prefix argument (default 1)
199 ;; It recognizes 0x... as hexadecimal numbers
200 ;; [M-k] kills the rectangle as normal multi-line text (for paste)
201 ;; [M-l] downcases the rectangle
202 ;; [M-m] copies the rectangle as normal multi-line text (for paste)
203 ;; [M-n] fills each line of the rectangle with increasing numbers using
204 ;; a supplied format string (prompt)
205 ;; [M-o] opens the rectangle by moving the highlighted text to the
206 ;; right of the rectangle and filling the rectangle with blanks.
207 ;; [M-p] toggles rectangle padding, i.e. insert tabs and spaces to
208 ;; make rectangles truly rectangular
209 ;; [M-q] performs text filling on the rectangle
210 ;; [M-r] replaces REGEXP (prompt) by STRING (prompt) in rectangle
211 ;; [M-R] reverse the lines in the rectangle
212 ;; [M-s] fills each line of the rectangle with the same STRING (prompt)
213 ;; [M-t] performs text fill of the rectangle with TEXT (prompt)
214 ;; [M-u] upcases the rectangle
215 ;; [M-|] runs shell command on rectangle
216 ;; [M-'] restricts rectangle to lines with CHAR (prompt) at left column
217 ;; [M-/] restricts rectangle to lines matching REGEXP (prompt)
218 ;; [C-?] Shows a brief list of the above commands.
220 ;; [M-C-up] and [M-C-down] scrolls the lines INSIDE the rectangle up
221 ;; and down; lines scrolled outside the top or bottom of the rectangle
222 ;; are lost, but can be recovered using [C-z].
226 ;; The final feature provided by CUA is the "global mark", which
227 ;; makes it very easy to copy bits and pieces from the same and other
228 ;; files into the current text. To enable and cancel the global mark,
229 ;; use [S-C-space]. The cursor will blink when the global mark
230 ;; is active. The following commands behave differently when the global
232 ;; <ch> All characters (including newlines) you type are inserted
233 ;; at the global mark!
234 ;; [C-x] If you cut a region or rectangle, it is automatically inserted
235 ;; at the global mark, and the global mark is advanced.
236 ;; [C-c] If you copy a region or rectangle, it is immediately inserted
237 ;; at the global mark, and the global mark is advanced.
238 ;; [C-v] Copies a single character to the global mark.
239 ;; [C-d] Moves (i.e. deletes and inserts) a single character to the
241 ;; [backspace] deletes the character before the global mark, while
242 ;; [delete] deltes the character after the global mark.
244 ;; [S-C-space] Jumps to and cancels the global mark.
245 ;; [C-u S-C-space] Cancels the global mark (stays in current buffer).
247 ;; [TAB] Indents the current line or rectangle to the column of the
