46 | This Lisp code will, when executed, define the kbd macro with the same |

137 | |
138 | When called from lisp, this function takes two arguments TOP and | |
139 | BOTTOM, describing the current region. TOP must be before BOTTOM. | |
140 | The optional third argument MACRO specifies a keyboard macro to | |
141 | execute. | |
142 | ||
143 | This is useful for quoting or unquoting included text, adding and | |
144 | removing comments, or producing tables where the entries are regular. | |
145 | ||
146 | For example, in Usenet articles, sections of text quoted from another | |
147 | author are indented, or have each line start with `>'. To quote a | |
148 | section of text, define a keyboard macro which inserts `>', put point | |
149 | and mark at opposite ends of the quoted section, and use | |
150 | `\\[apply-macro-to-region-lines]' to mark the entire section. | |
151 | ||
152 | Suppose you wanted to build a keyword table in C where each entry | |
153 | looked like this: | |
154 | ||
155 | { \"foo\", foo_data, foo_function }, | |
156 | { \"bar\", bar_data, bar_function }, | |
157 | { \"baz\", baz_data, baz_function }, | |
158 | ||
159 | You could enter the names in this format: | |
160 | ||
161 | foo | |
162 | bar | |
163 | baz | |
164 | ||
165 | and write a macro to massage a word into a table entry: | |
166 | ||
167 | \\C-x ( | |
168 | \\M-d { \"\\C-y\", \\C-y_data, \\C-y_function }, | |
169 | \\C-x ) | |
170 | ||
171 | and then select the region of un-tablified names and use | |
172 | `\\[apply-macro-to-region-lines]' to build the table from the names. | |
