It doesn’t really have anything to do with PDFs. Drag and drop always works. The issue is that Adobe Reader does not support AppleScript; thus, it cannot work with EagleFiler’s capture hotkey. If you use a PDF reader that does support AppleScript, such as
Skim, you will be able to import via F1. You can also use F1 to import a PDF file from the Finder.
Since that’s not correct, it would be great if you could tell me the URL of that forum.
This is a way to import text (as well as other content, e.g. a selected image) from most Mac applications.
On a U.S. keyboard, the % symbol is accessed by holding the Shift key and typing the number 5.
The “EagleFiler: Import” service works with any Mac application that can send text. Unfortunately, I don’t think Adobe Reader supports the OS X Services feature. Again, there are other PDF readers such as Skim and Preview that do support Services.
