Read the question carefully I'm asking how to open the Find/Change
dialog, not how to toggle it.
Toggling is easy enough:
But if it is open, this will close it, and vice versa.
I'm wondering if there's any way to specifically make sure it's opened?
This probably won't help but see https://forums.adobe.com/message/4413557#4413557
If you could perform some action that will fail if the panel is closed then you could use a try catch to determine its state.
I'll leave it to you to think of what that action would be.
Thanks for the link. Looks like Peter Kahrel was looking for the same
thing a couple of years ago, but if he found an answer, I don't know.
There's no answer in that thread there.
I had thought of the idea of invoking something that doesn't work when
Find/Change is open, but I couldn't find anything!
Yep, I couldn't think of anything either, that's why I wrote that I'll leave it to you.
Probably it's a "no can do"
I suggest you either send a mail to Peter or a a post to that thread
