Is there a shortcut key to switch between Parameters and Exceptions tabs in Change Signature dialog?

I really love the fact that Change Signature dialog is so shortcut-driven, but when it comes to change the throws exception stuff I have to grab the mouse.
I've tried the CTRL-TAB (CTRL-SHIFT-TAB), hover over the tabs to get some shortcut info, but without any success.

Is it possible to switch between these tabs using a keyshortcut?

Thank you in advance
