Those symbols...

[CherryViz]

You write o + ¨ = ö whee
Easy right?  

[eightythreex]

you can change your keyboard layout to swedish in the control panel.
an easier way of doing the symbols with alt keys is:
alt + 148 = ö
o with umlout
alt + 132 = ä
a with umlout
alt + 134 = å
a with circle "thing"

Hope this helps.
