Photoshop: Keyboard shortcuts for swatches

Question

I would like to assign a different keyboard shortcut to each of the swatches that I load by default in my Photoshop projects.

I can do this recording by recording a different Action for the selection of each swatch and then assigning keyboard shortcuts to each of the recorded Actions. However, if I understand correctly, the keyboard shortcuts for Actions must use Function keys, which I do not find convenient (they are usually not near my fingers on my keyboard).

So here are my questions:

1. Is there an alternative way of assigning keyboard shortcuts to swatches in Photoshop (instead of recording actions)?
2. If not, is there a workaround that could allow me to use keyboard shortcuts for actions that do not involve Function keys?

Thanks
