This program is exactly what I was looking for besides one major short coming.
I can't understand, or it is impossible, how to scroll vertically with the keyboard.
The only way I know is using the mouse, but many times it is much easier using the keyboard.
The program supports horizontal scrolling with the left-right arrow keys, why not vertical
using the up-down keys, and leave moving to the next page to page-up/page-down and the myriad
other ways.
So am I missing something or it really is impossible ?
