What memory card size should I get for my PS VITA?

I got a ps vita and now I need a memory card. I don't wanna pay more than I have to. I probably will get a 16gb since 80 bucks for a 32gb is quite a lot. I plan to buy all my games in retail, so I won't get full on ps vita games off PSN. However I do plan to get minecraft, terraria, and spelunky. Is 16gb good for that plan? Or should I invest in a bigger memory card?

How to set up macros/keybinds?

I was wondering if there was a way to set up a macro on my mouse. I have a mouse with the 2 buttons on the side to go forward and backward. I was wondering if there was a way to make it so when I hit one of those, it activates the 9 key. I need this because I play minecraft and I want to be able to switch to the 9th slot on my hot bar just by pressing one of the 2 buttons.
