Using Your Newly Made PDF
After you click "Export", you're basically done- that is to say your PDF is done being made, with the actual creation of the file. Now, in essence, you know how to create searchable PDF for Mac OS X, but do you know how to use it?
After you export the file, you'll need to locate it in your computer, but it should be located right next to where you saved the original file, so that shouldn't be too hard. After you located it, right click on it, select "Open With", and then choose the program "Preview" from the drop down list. This ensures that the file you created will be opened with the right program.
Next, you'll want to press the hotkey "Apple+F". If you're unsure what this means, look at the button directly to the left of your spacebar. It should have a picture of an apple on it. If you hold that down and push the "F" key on your keyboard, you should see a small box come up. Type in the word you're searching for, and it should take you to the first entry of that word in your PDF. There could be multiple pages, so if you need to scroll through them, hit the "Return" key however many times you want to look.
