This should be common sense, but many people do not know.
Okay, many people use guides, and have to constantly alt+tab in and out to get something done, whether it be looking for coords, or just reading it.
Something to help you alt+tab left often is get the Cartographer addon, or any other that lets you plot coordinates on your map. The reason I enjoy Cartographer is because you can make it show an arrow in the middle of your screen telling you the direction, so you do not have to use the world map as much.

Once you have it downloaded, load up your guide and start plotting coordinates labeling them, 1, 2, 3, 4, ect. ect. You can then follow the route to finish your quests quickly without having to look around.
Another way
You can copy paste an entire section into the "Notebook" section of Cartographer, so you do not have to alt+tab at all.
Hopefully this has helped you or will help you, good luck in leveling, one step to make it easier.
