I can't seem to use Hookmark effectively

OK. I copied and pasted the answers below.

What video app are you using? Currently Hookmark supports deep linking in a QuickTime Player.

For PDFs deep linking, Hookmark supports deep linking in Skim, Adobe Acrobat reader and Nitro PDF. For Adobe reader, the deep linking only works for annotation. For other pdf apps, you just select some text in the PDF document, bring up Hookmark window, then you can do copy link or link to other documents.

For file path, you can get it in Finder

  1. Control-click or right-click on the file in Finder.
  2. Press the Option (Alt) key.
  3. Choose ‘Copy [filename] as Pathname’ where [filename] is the name of your file.
  4. Paste the path wherever you need it.

You can also get it in Hookmark. Press option buttion, you can copy file URL.

Sorry it means Invoke Hookmark first, then hit CMD N

The bar inside the red rectangle. Sorry this is confusing.
