The Sumatra PDF viewer comes as one single .exe file, and is about as minimal as you can get… it launches in less than a second for me, and the clean interface is great. 

But that’s not the best part… it’s got shortcut keys that are very similar to Gmail and Google Reader. (Except j and k are swapped for some unknown reason)

Here’s the list of shortcut keys: 

space – scroll by screen backspace – scroll back by screen k – scroll by one line j – scroll back by one line Down – scroll by one line Up – scroll back by one line n – goto next page p – goto previous page Page Down – go to next page Page Up – go to previous page g – goto page q – quit + – zoom in – – zoom out r – reload PDF document + – rotate clockwise – – rotate counter-clockwise Home – go to first page End – go to last page

Just being able to navigate a PDF with the same keys I use all the time was enough for me.
