Shortcut keys

I was wondering if there was a resource for ALL short cut keys?
This way I could print it out and use them whenever I like.

For example in a previous post I found out thant Command +Option+I
shows the combined size of multiple files.....I never knew that, I was always trying get info and seeing multiple windows open....

Thanks
