this ref card misses some of the point:

A ref card needs to contain a lot of info in a limited space.

So why waste space on pics of the writers, on adds for other ref cards, on picutures of the writers, a blue left margin ?

Suggestions:

no "about",

no pictures and life stories of writers. I don't wanna see them every time i look up a keyboard short cut

forget about how to get netbeans. Using the ref card presupposes having netbeans..

No quick start: you can find it on the net.

forget about the MAC.

no recommended books.
