Swap My Fill and Stroke Colors in a Snap?

If you’ve been adjusting a stroke color and then decide you want to swap it with the fill color, you could head over to the Toolbar or Swatches panel and click on the Swap Fill and Stroke icon (the little double-headed arrow above the Fill and Stroke swatches), or you could simply press Shift-X. This swaps the colors, or in other words, makes the fill color the stroke color and vise versa. Just pressing X will toggle between Stroke and Fill, but it won’t swap the colors. Pressing / (forward slash) will remove the color value from whichever one is currently selected.
