After you look at the pictures and wonder what your even looking at here.
#1. Go into WoW and for example set yourself into a chat setting like guild or say by typing in /s or /g then enter.
#2. Then when u have it like when u press enter [Guild]: or [Say]: comes up then press enter again so the little chat box is empty is not there.
#3. Then press both "/" and enter at the SAME TIME.
#4. When you do that. The small slash mark(or back slash) should stay there.
Idk it's not anything special but whatever i thought i'd post i thought it was cool :P
If you think this is pointless or whatever please ask for a remove or something but imo its pretty cool. Have fun with whatever you can do with it. Also you can do it with trade chat. I guess you can use it to keep track of what track u were alrdy in if u could make some program to press it to make sure you know what chat your in. Idk mess around with it. Its for you community. I'm sucky at finding these cool things but blah here!
