Quick, clean, and to the point

Extend selection left one screen

Windows shortcut 
AltShiftPgUp
Mac shortcut 
Fn

Extends the current selection one screen to the left.

Note: this shortcut is unusual on a Mac because the Command key is required (Option doesn't work), even on Macs with Page Up / Page down keys.
