RFE: a couple more Quick Look shortcut keys

This change was made in 2.4 (thank you!):

• Improved: Page Up/Down keys can be used to navigate inside a visible Quick Look panel without having to activate it via the mouse first.

Please also enable Home/End keys (Fn-LeftArrow/RightArrow on an Apple Bluetooth keyboard) for navigating to the beginning/end without mouse activation, making them behave consistently with other QL contexts I frequently use. Thanks again!

Thanks for the suggestion, the next maintenance release will support these shortcuts.
