Ferlin, Use the options in the brush palette to rotate the brush.
Just click & drag on the arrow on the circle.
Click and drag on the dots to narrow the brush.
You can also set options for various settings when using a Wacom, find them under Other Dynamics. Just set the control you are interested in to pen pressure or pen tilt.
I use ScreenSnapz Pro for screenshots, (Mac).
You could try Print Screen on the PC, open it in Photoshop, crop to the part you need and use Save for Web.
Al.
PS. Only dumb question is the one that is never asked.
