How to Bookmark a page in a PDF document

The Easy Way to Remember a Page in Adobe Reader

Adobe Reader does not let you create and place new bookmarks, but there’s one little setting you can apply that will help the software remember the last page that was opened by the PDF reader. It is ‘technically’ not a bookmark, but it’s a handy workaround that takes just a checkmark. Follow the steps below to enable the native feature.
1. In Adobe Reader, go to Edit – Preferences (or CTRL + K).
2. Click on Documents under the listed categories on the left.
3. As shown in the screenshot, enable the feature that says – Restore last view settings when reopening document. Click OK and exit.

Enjoy!!!!!
