To select text in the microB browser, slide in from off the left-hand side of the screen to just on the screen. An arrow icon will appear. Tap it, and you will then be able to select text in the browser as if with a mouse on a PC (i.e. click and drag to select text). Ctrl-C copies to the clipboard. Repeat the slide-and-tap-icon process to go back to normal mode.

If my explanation is deficient, please post back here and I or someone will try to help further.
