Dear All,
Could someone here help me creating a particular function in
AUCTeX-preview? Also, I wonder if such a function would be
of interest to other people too, to submit it as a feature
request:
In Preview, it would be useful to have a function that
toggles on/off the visibility of all previews in the buffer,
independently of the position of point. The key word here is
*toggle*, rather than *regenerate*.
The function preview-at-point only toggles one preview, and
only if the point is positioned on the preview. So if one
only needs to take a quick look at the LaTeX code of a
couple of formulae above or below point, one must:
1. move point to the preview,
2. call preview-at-point (or mouse-2),
3. take a look and memorize the code of interest,
4. call preview-at-point,
5. move point back.
The other option is to clear all previews (say in the
section) and then regenerate them – but this can take time
in buffers with many formulae, and is simply a waste of
resources.
I tried to use/reverse engineer the functions
"preview-at-point" and "preview-toggle" to build a function
that toggles all previews at once, but failed (I don't
understand how the "overlay" argument works in those
functions). If anyone can suggest a method to do this, I'd
be very grateful!
Cheers,
J
