Hi there need to use some tape to get some strait lines, i read somewhere about a trick, using tape and caulking (to seal edge) to achieve this. Can somone please explain how the caulking trick works?

The idea is to seal the edge of the tape to prevent the paint from bleeding. What are you painting.. a stripe, against trim, two different colors?
I would like to paint a nice strait line against my trim and casings. If you seal with caulk woul this not leave a slight ridge?
You still want to caulk with acrylic latex caulking prior to painting. Wipe clean with a wet finger. Paint the trim first. Now while looking at the wall you should be able to paint a straight edge without taping anything. And the caulking ridge is too small to notice or hinder this process. use a quality brush. A small artist brush can be used for more precision if needed.
Something that helps is to be on a good step ladder close to your work. Limit the coffee, take short breaks, and keep the brush base clean.

For freehanding:
-Lock your wrist, and paint with your shoulder or elbow(whichever is in better shape lol) in a twisting motion.
-Load you brush, and put on a thich ridge of paint 1/2 inch away from your line.
-Use that "resevoir" to siphon paint to the applying edge of the brush, usually near the center of the brush not the end.
This edge will consist of a bundle of 4-10 hairs which reinforce each other.
-The size of the brush sometimes doesn't matter. A 3" holds more paint than a 2" and be faster depending on the job/area. For me, a very small brush shows my shaky hand, and I get tired of dipping.
-Don't push hard. Spread it with 4-8in strokes with a slight curve at the begining and the end.
-If you get a blob of paint, get rid of the paint in the brush elsewhere, and brush underneath it to deflate it.
-If paint gets on the trim, wipe off and redo later.
-First, smooth and/or fill in the the edge before, for a clean line. Knock off the high spots with 60-220 grit wrapped around a paint stick, and smooth it out with caulk(flexing problem areas) or spackle(I prefer). Let dry to shrink, and touch up if necessary. I wipe spackle briefly with a wet cloth.
