Freeware Shorts: SumatraPDF
SumatraPDF (Version: 1.7 as of this post) is an open source PDF reader for windows. It is, as it claims, fast and simple.
It features command line support and plenty of shortcuts for document navigation, viewing and more. A list of all shortcuts are available via the program’s manual page.
SumatraPDF can also read XPS, DjVu, CBZ, CBR and LaTeX documents. It is also capable of remembering the last read page so the next time a certain PDF is opened one can return to that page. One of the more recent features added is favorites – which can be set to not only specific files but also pages within them – with the ability to show thumbnails of recently viewed documents. SumatraPDF can open protected PDF files and has the familiar layout and zoom settings as well as a full screen mode.
