I'm still trying to 100% figure this one out. Open your colour pallet and selec a base colour for your background so you can work on it and paint bucket it into your work area. Leaving the pallet window open on RGB, go to file then preferences. Click the layers tab and click the box with colour in it. Copy the RGB values for your bacground colour into the boxes and click okay.

When I usually do this I usually already have a sprite drawn, so I copy the sprite out of the layer, cover that layer completley in my base/background colour and paste the sprite into a new layer. I then use the magic wand to select and delete any filled in areas of background colour the sprite may still retain (click the hide/view layer button on your background layer to make this easier).

If I figure it out completley I'll repost

That's done in the frames section (even if it's not animation). Click the ... thingy next to the frame square where the drawing goes and click on enable transparency , then it will ask you to choose wich color will be the transparent one. You will see in the preview that the color you chose disapears, thats the transparency.
