So I'm looking at the keysyms in SDL and I see a set of about 90 SDLK_WORLD... keys. I can't seem to find any info on what these keys actually are on the keyboard.

SDL supports the multi-national keyboards directly, passing back non-ascii keys as the SDLK_WORLD* keysyms. Did you have a particular SDLK_WORLD* key in mind?

I later realized that I was looking at old SDL docs pre 2.0 while I'm actually using the newer SDL and the WORLD keys are now gone.

I don't even know what SDLK_WORLD key to have in mind though since I literally have no idea what that means. I guess I'm still curious what it means even though.

My closest guess is maybe a keyboard with a Chinese character or something.
