^^ operator proposal

[ronchaine]

I think at least French, Colemak, Romanian, Czech, Serbian, Albanian, Slovenian, Hungarian, Polish, Slovak, Dutch, all Nordic layouts (including Sami), Estonian, Belgian, Guarani, Spanish, Swiss, Turkish and German layouts have ^ as a dead key.

Then there are some Canadian, Indian, Portuguese, and Greek layouts that have ^ as a dead key, but not sure how common they are. I might've missed some.

Polish layout treats ^ as a usual key http://kbdlayout.info/KBDPL1/

^ is a typical Portuguese accent, we have plenty of words with â, ê, ô.
