Not within FileMaker itself no. I'd suggest you fill in a feature request for this, you're not the only one who would like it. : http://www.filemaker.com/company/contact/feature_request.html
You can script this process with UI automation tools like QuicKeys though.
Thank you for the reply. I hadn't heard of QuicKeys but I took a look at it and it seems like it would do the job.
By the way I did write a feature request.
