Hi All,
Something yo may or may not do, which I inadvertenly came across yesterday (which I've now found to be incredibly useful). When studying and you are regularly accessing config guides and command reference docs, just add a couple of bookmarks to the relevant folders on your machine (not online) where your documents are stored.
This way you can open multiple pdf's /docs in tabs in your browser. Much easier to navigate than loads of taskbar icons etc.
