[Inkscape-user] Change stroke color with a simple click

I wonder if it is possible to change the behavior of the color palette as to change the stroke color (as opposed to the fill color) with a simple click.

I mainly write text+outlines, using the freehand tool and a wacom tablet and occasionally have to switch colors. It's inconvienent to reach for the keyboard and press SHIFT+Color click to do this, especially because my wacom's extra keys are bound to more important stuff than shift.

I hope this isn't a FAQ, but I didn't find it in there. And, if it's possible by editing some source code I'm willing to do so, but need a pointer.
