This week I started reading the Marco Cantú's Delphi 2007 Handbook, and it inspired me to make this cheat sheet.
I learned several new Delphi 2007 shortcuts that helps a lot to improve productivity.
I made a compilation of the shortcuts which I think are essentials to every Delphi developer.

Just a few comments about some of the shortcuts:
Ctrl + /: This slash is the phisical slash key, it is located on the left side of the right shift key.
Ctrl + O, U: This shotcut inverts the case so CaSe becomes cAsE, you have to select the text, press Ctrl + O, release the Ctrl key and then press U
