Key Commands for Right Zone Categories

I’ve scoured the key commands with no success looking for the category boxes in the Media tab of the right zone shown in the attachment.

I have a key command for Import Audio but that feature has been greatly diminished in C10. I am using the File Browser category under the Media tab in the right zone to replace it and miss the speed of having a key command to select it.

I’m loving the new drag n drop and pictures feature in the right zone for VST Instruments and Effects and hot keys to select between these categories would be great for work flow as well.
