P: Ability to browse the presets and see its effects with the up and down keys

Can you not use Mac's built-in features - I've forgotten how to call them at the moment, but maybe you don't need anything extra (?).

Also, I think Keyboard Tamer will do it, no?

hmm. looks like knobroom is only for a midi controller. Trying not to spend more money. Any other suggestions for freeware/plugins?

Yeah I was thinking native LR function, and I just looked into paddy and I am on a mac, so I am going to try Knobroom. It seems like such an easy way to add so more functionality.

I realize this request is for native Lr functionality, but in the mean time: I think the Paddy plugin supports this, no?

Please allow customizable functions/hotkeys for presets. That would speed up workflow so much. Having to mouse across a huge screen takes a lot of time. And even being able to arrow in between them would be cool. I want to assign to function keys like you can actions in Photoshop! imagine being able to use your keyboard or shuttle to apply your custom presets. If lightroom is about workflow this is one of its major flaws.
