Quickie - PDFs - middle mouse button

Here's a quickie. Most may already know this, but I didn't so surely someone else doesn't, :P. When using a PDF reader (at least for Okular and Foxit) you can click the middle mouse button on the scroll bar and it will take you to that area of the PDF.

edit: This also works for any window in Ubuntu (and maybe for Windows too?). I feel lame that I didn't already know this, :P.
