Xubi likes the typing animation, she says, becauase it lets you know when another avatar is preparing to say something in Chat.
Chey hates it because the thinks typing in the air makes her avatar look like it is putting quote marks around everything.
You can buy typing animations that replace the default typing anim with laptop animations or particle effects, and some animations suppress the typing anim; if you put the latter in your AO, you will not type, so long as the AO is on. Which it often won't be.
With our special investigative powers, we have figured out how to permanently suppress the typing animation! Woo hoo!
Go to the Client menu and select DEBUG SETTINGS (if you have no CLIENT menu at the top of your screen, CTRL-ALT D on the PC and CMD-ALT-D on the Mac).
Click on the little down arrow and scroll down to PlayTypingAnim and set it to FALSE.
No more typing animation, even after relog.
If you want to turn it back on, just reset it to True.
