I was reading a book and wanted to copy some text from it. In FBReader, a long press brings up text selection.

I dragged the right side marker to expand selection. While dragging, my finger went into right bottom corner and I was surprised!!!

The screen scrolled one line. I was intrigued. I grabbed the selection bar once again and repeated the action. But this time I did not let go. The screen continued to scroll and I managed to select a large portion of text.

Very nice feature. Love it!!!
