Describe the solution you'd like
As described in a different feature request a year ago that I'm finally following up on, I'd like to be able to type a single command to have vimtex open the bibentry for the citekey under the cursor in BibDesk (on MacOS). This would of course only work when the latex project open at the time refers to a .bib file.

Additional context
I briefly summarized the protocol for interacting with BibDesk here.

Sorry that is has taken me so long to open the feature request! I hope this is feasible without too much trouble.
