 Tip:  Mineral-Walking

How often have you been rushed (damn you Zerg and your 6 pool Rush) and either haven't enough to deal with it or just been on the verge of getting another unit out.  Your probes can't out run those little zerglings so what are you going to do?

Try mineral-walking to stall and get that extra unit out.

Here is how you do it (very easy).  It only works with probe/drone/SCV but all you do is select a mineral patch and boom your unit can walk through other units to get to that mineral patch.  So it works in your own mineral line if you have some pesky zerglings attacking you get them to follow you to one side of the mineral patch and then once they are near you click on a patch on the other side of the mineral line and you will warp through them - keep doing this until you get enough units out to deal with them.

Or it could be a scenario like this where you want to get your probe/drone/SCV into the enemy base to do some scouting but they are blocking the ramp. 

Here's a video example (not mine) of this concept in action.
