Nope, not as far as I know, but if you don’t change your window layout much you could make a simple www.autohotkey.com script to click it.
I made some subroutines to save and restore the mouse position cause click changes it, if you’re interested I can grab them when I’m at work tomorrow. (I mostly use AHK to cover gaps in our crappy in-house software and automate bits of web-forms, so most of my code for it’s there.)
Dunno if you can change the state of that in python… and if you can, I think the only way might be a spacehandler responding to keyboard hits? Dunno what you can do if anything like AHK on there either.
Python and scripting is way over my head at this stage, so I guess my hand will have to run the marathon a little longer, until the awaited 2.50 with it’s customizable hot-keys…
