It's fairly simple, you set the direction, leave it for a small time and abort. Highly dangerous, I do not suggest doing it without practicing in deep space first.
It is my perception that there are two versions of microjumping;
1. In-system micrjumping is when you attempt to reach another loaction, within the same system, by taking a short trip to hyperspace, like Derrik said.
2. Out of system microjumping is if you, as an example, exit hyperspace into galactic position (10, 10), system position (19, 19), aka lower right corner. If your ship has a very low sublight, and the in-system destination is (8, 8), you will use many hours to reach it from (19, 19). In this case you can hyper over to glactic position (9, 11), and then hyper back to (10, 10) once more, this time appearing at in-system coordinates (0, 0), which is a bit closer to (8, 8) than (19, 19) is.
Option 2 is somewhat HS level dependent, in that a ship with HS 3 and sublight 20 will save more time than a ship with HS 2 and sublight 20. Ships with low HS and high sublight don't have much to gain with this technique.
Not really much to learn: pick the square on the side you are wanting to get close to (ie, the {empty} system next door) and start hypering; wait a few seconds/minutes and abort; pray you didn't end up in a sun/planet/solid celestial object and maybe try again
Usually safest to practice in an empty square (greatly reduced risk of going *splatch* when you abort)
We're working on doing a bunch of updated guides and potential video-tutorials for all sorts of in-game aspects. I'll see about the possibility of doing one for micro-jumps. It will probably be done and released (if done at all) after you would likely need it, but for future players it's certainly a possibility!

I am upset things like this happen. I get upset over every godamn thing. ~ Any given SWC player on any given day.
Didn't know you could micro-jump, would have been much better than jumping to the square next door (using the system Metyl showed) and aborting and hoping to at least be heading in the right direction (ie start in the bottom left corner, hyper to {+1X, +1Y} hoping to get closer to centre {and shaving several hours off of sublight} only to find mahself in {-1X} or even {-1X, +1Y})
Tiali, you probably realise this but I'm quite sure the abort function doesn't care what direction you're hypering in when it randomly selects where you'll come out at in the system.
That image should be clear enough for anyone, I don't see how a video could make it any clearer when they'd already have learnt how to actually enter hyper by then. Though whilst still technically correct the -Y should be -1Y to match how the other locations where written but that's just being picky it doesn't actually matter.
To my knowledge it is not random but in fact calculated.
I am guilty of doing a few of those little in-system hyper/aborts (personal ships) before, and you can control the direction. Just not the location on that trajectory.
