Using Fn triggered blue numpad keys for navigation on your laptop

Laptop keys are usually cramped and accessing the usual arrow and page keys are a hassle. I find it useful to use the "numpad" triggered by Fn key.

Fn + 7 = Home
Fn + 1 = End
Fn + 9 = Pg Up
Fn + 3 = Pg Down
Fn + 8 = Up
Fn + 2 = Down
Fn + 4 = Left
Fn + 6 = Right

Scrolling in Screen session

# To enable scrolling in Screen session you have to get into 'Copy mode'
CTRL + a + [
or
CTRL + a + ESC

# To scroll, use VIM methods

Left, down, up, right --> h, j, k, l,
Page up, page down --> Ctrl + f, Ctrl + b
