It would be nice to have a short-cut key for toggling the tools palette instead of clicking view->tools palette. I know several people have included versions of this in request for larger changes to the UI but I haven't found this request by itself.
Not a keyboard shortcut, but Shift+Right Click is my preferred method of getting to the Tools palette. This has the added bonus that the Tools Palette pops up where your mouse is so you don't have to go searching for it.
Additionally, you can set your own custom keyboard shortcut to the Tools palette in Tools>Options>Menu Shortcuts.
Since the only possible thing you can be doing with the Tools palette is changing the cursor of your *mouse*, I'd say Shift-Right Click counts as a keyboard shortcut. 😉
