How to 'Select All' using the keyboard? Is there a way - using key commands - to select all?

I have a sphere that has some vertices deep inside that only appear when I move the ball, and they are not selected no mater if I use the C or the B select keys.

If I could "select all" the program should be able to get these little rouge vertices that I can not seem to collect when I try either C or B. 

Thank you
Yes, you can select all with A.

If there is anything selected then A will deselect everything, if nothing is selected A will select everything.  You can change this behavior immediately after pressing A at the bottom of the T toolbar, or with the F6 menu.
