I wasn't actually talking about Terraria in general lol, I had just recently logged on and saw that a very old community (one that i hadn't even been a part of mid you) had been shut down and it just reminded me of this.
As for Terraria's possible death, I'm still hanging on to TF2, I'll be...
Most people still have z bound to the quickbuff so maybe f to scroll through the ammo slots. Also, if you have half of your ammo slots taken up by arrows and the other half by bullets, holding a gun and pressing f should only scroll through the bullets and the same with bows and arrows.
