I've tried to remap such keys as "export"(command+shift+e) keyboard shortcuts in LR 4.3 using the System Preferences>Keyboard shortcuts trick but Lightroom does not allow remapping. How do I remap the keys in LR on 10.8.3? Very frustrating.
I switch between Photo Mechanic and Lightroom and use textexpander to switch between programs by pressing the "~" key. Switching to LR using "`" key works in Photomechanic but LR overrides the use of the "`" key as a "flag" pick key. How do I override LR keys?
I've even used Keyboard Tamer but that doesn't work.
I don't think you can natively do the keyboard mapping. However, in the past, I've tried a plug-in ("paddy for lightroom") and it allowed you to map some LR functions to keys; but it didn't always work for me.
