Simple Powerpoint Vba macro

Job ID: 35941379

Budget: ₹750 – ₹1,250 INR

Hello, I need a very simple Vba macro, but it is in Powerpoint and I am not able to do it.
I have a table or a part of a table already selected, then the macro will format:
Font Calibri 12
Center allignment orizontal and vertical
Cell margin “normal”

I want to start the macro with a button in the quick access area, and, if it is possible, with a key combination, as “Ctrl+Q” or other key confortable with the left hand, ie “Ctrl+1” or “Ctrl+W”.

I use Powerpoint 2007.
