Quick exposure editing keyboard shortcut in Library mode?

Hello,

I've been using Lightroom for a very long time and I think it would be extremely helpful to have a way to go through images in library mode (loupe mode) and be able to quick develop exposure with +/- 0,10 increments wihtout using a mouse. Ideally going through single images (in loupe mode) with left/right arrows and change exposure quickly with the up/down arrows.

Right now the only way to do it is in develop mode (I just increase the exposure on the first image with the arrow key and then go to the next image and still i'm able to increse/decrease exposure as long as I don't move to a different slider) but it's much slower to go through images in develop mode. 

If there is a way already please let me know!

Thanks
