I just got a new approach to solve your problem - what about a symlink in your documents base directory? An entry in the content lister which takes you to your wanted document.
As soon as you open a new bibliography entry on your PC, a script replaces the existing symlink via SSH to point to the new PDF. This way you can open it in the content lister with 1-2 clicks and get around those key event issues.
Basically, it's something like
Code:
ssh -l root (iliad's ip) "rm /mnt/free/documents/0_actual; ln -s /path/to/your/new.pdf/ /mnt/free/documents/0_actual"
(didn't try this code, but I hope you know what I mean)
