    <p>I have the following Emacs macro, which evaluates the AucTex command <code>TeX-insert-macro</code> on selected text:</p> <pre class="lang-lisp prettyprint-override"><code>(eval-after-load "latex" '(progn (define-key LaTeX-mode-map (kbd "C-c (") (lambda () (interactive) (TeX-insert-macro "command"))))) </code></pre> <p>However, how would I perform a regexp on the selected text and pass that to <code>TeX-insert-macro</code>?</p> <p><a href="https://tex.stackexchange.com/questions/136563/command-emacs-selection-commandregexped-selection">See this question for more details.</a></p> <p>For example: Suppose I have the following text:</p> <blockquote> <p>…as shown in figure (24).</p> </blockquote> <p>Now, suppose I select "(24)." Then, I want a command to convert it to:</p> <blockquote> <p>…as shown in figure \command{eq:24}.</p> </blockquote> <p>Viz., how would I define a new Emacs command that I could place in <code>~/.emacs</code> that would run <code>C-C RET command RET</code> on a regexp'ed version of the selected text?</p> <p><strong>Why doesn't the following with regexp work?</strong></p> <pre class="lang-lisp prettyprint-override"><code>(eval-after-load "latex" '(progn (define-key LaTeX-mode-map (kbd "C-c )") (lambda () (interactive) (query-replace-regexp "\(([0-9]+)\)" "\1") (TeX-insert-macro "eq") )))) </code></pre> <p><strong>Minor improvement:</strong></p> <p>This works well if I select, e.g., "(45)" from the left to the right and then run the code by typing <kbd>C-c )</kbd></p> <pre class="lang-el prettyprint-override"><code>(eval-after-load "latex" '(progn (define-key LaTeX-mode-map (kbd "C-c )") (lambda () (interactive) (exchange-point-and-mark) (replace-regexp "[\(\)]" "") (TeX-insert-macro "eq") )))) </code></pre> <p>However, if I select "(45)" from the right to the left, it doesn't work because the point and mark are flipped. Is there a way to make sure the point and mark aren't flipped, such as by running <code>exchange-point-and-mark</code> when they are flipped?</p> <p>Also, there are other issue with the regexp, e.g., if there are other parentheses nearby it gets greedy.</p> <p>thanks</p>

    1. COThe question is a bit confused. There are no macros here, other than (one presumes) `TeX-insert-macro`; and you cannot "perform" a regular expression.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
