Starcraft 2 Skills: Hotkeys for Map/Camera with F5 through F8, & Worker Micro & Tips/Tricks with F1

Though a lot of people don't realize it, you can use F5-F8 to hotkey a camera view of the map.

See http://wiki.teamliquid.net/starcraft2/Hotkeys#Camera_Hotkeys for clear explanation.

This is useful for scouting, you can hotkey potential enemy base locations, so you can view it whenever you have vision (ie using different scouting units on patrol, so you don't have to hotkey each scouting unit).  Terran can tie it in with Scan very nicely!

You can also use it for mineral line for a 3rd or 4th base, so you can transfer workers faster and more efficiently (F1 will select idle workers, Shift + F1 will select all idle workers).

Embedded VOD below from SC2NoobSchool shows how to Transfer workers effectivly to gas or to a new base.
