[OS X TeX] pdf viewers: pop-ups at hyperref links

Sun Jul 10 15:36:54 EDT 2022

Hi Richard,
...

> Skim does have an additional tool though. (I use single page view, and I’m not sure how this works with a double page view). If you hover the cursor over the link long enough for the pop-up to appear and then do a command-click on the link, Skim displays off to the side a window of a full page width view of the lemma or whatever, but only maybe ten lines long, and it’s scrollable vertically. Then I can examine the text on both pages side by side and determine whether or not, for example, the lemma really does imply what I said it does.

This is great! I had seen this side window many times before, by
accidentally hitting  some keys in some rush typing. Now, I know that
this is by cmd+click and what it is!

In this side window:

- I can scroll through the entire pdf in it
- I can resize it
- From the top menu bar of Skim, I can:
PDF > Zoom In / Zoom Out, alternatively, I can use:
 cmd + / cmd -
- It is a 2nd window display of the same pdf. (Up to now, I have tried
many times, without success, how to bring in a 2nd window display of
the same pdf, in Skim, and in Preview)
- I do not know how to Toggle the ToolBar on its upper part. But, this
may be good, to distinguish this "side window" from the primary one.

> The one thing that annoys me about this though is that I first have to wait for the pop-up to appear. If I command-click before the popup appears, a tiny useless window pops up. I believe that at one time I used to be able to do a command-click before the pop-up appeared and it worked properly, but at some point it stopped working properly.

With my Skim (Version 1.6.11 (141)), the side window appears without
waiting for the small pop-up window, just by:

cmd+click
- I get a side window, full width, 7-8 lines
- I get a 3rd, 4th, 5th (I havenät tried for more cmd+click :-)

This is an excellent feature - thanks Christian, hoping you read this,
and will try to do something with the pop-up small window, to get the
entire math display displayed in it.

Richard, thanks for telling us about it.

Dick, now TexShop should get this feature as well.
