Add possibility to scroll the screen

[re1neke]

I try to run impala on a Raspberry Pi-driven machine with a 5" screen, which adds some restrictions to my terminal: it has a size of ~80x20 symbols, and as a result, the "New Networks" section can't be reached, as there is no space left for it. It can be fixed by setting a smaller font size in terminal settings, but it makes me struggle to work with such tiny letters on such a tiny screen. :( Is it possible to add the ability to scroll the entire screen or just move the screen to the bottom on a Tab press when you select the appropriate section?
