As we all know many of the Arduino I/O pins have special functions. So it is a bit tricky sometimes to find the right pins to use for a project. Then the I/O pins are organised in "ports" and for many things you can benefit from putting groups of connections on pins that belong to the same port and program them directly. I'm quite new to the Arduino and don't know all the special capacities of all the pins by heart yet. So I wish to have some kind of cheat sheet, showing all the pins, the ports they are related to and all the special features of the different Arduino models. Any pointers?
Well you had the right terminology, did you g**gle?
That should be useful to you.
Many thanks to retrolefty and mowcius, this will save me some labor.
And yes, i did google, but with slightly different terms. I already knew the arduino cheat sheet too. I had looked on it for the port informations once, but forgot that there is other pin related info. Would be quite hard to find space to add the port information on that sheet, btw 
I see. Well glad you got what you were after.

Me too: Google Spreadsheet for Arduino
There's also a -free- app for the Android platform called "Electronica" that recently had an update to include a picture of the Arduino board with pinout labels. It identifies which pins are what (but not the port groupings, unfortunately).
The author is fairly responsive, though - so if you like the app (it has a bunch of other useful features - resistor codes, capacitor values, pinouts for other things, LED calculator, etc), you can tell him and he'll look into updates (its from hacsoft.com).
BTW: I don't see port A it in the pin lists. What is it used for?
