I see. What other combos does it support?
A few of the easier to remember:
option + 0 for degrees º
option + u for to place an umlaut over the next typed character (when it's a valid combination, anyway) ëüä
option + c for cedilla ç
Also if you need ad-hoc bullets, just reach for option + 8.

The difficulty in accessing symbols like these is one of my (I'm sure correctable) hang-ups when using Linux — Arch, btw.
