Weird Console Problem

[Jokis]

I'm sure there's a simple solution to this, but I'm just a retard.

 

I tried binding some taunt keys but I think I messed up, well one thing led to another and all of a sudden these red ^ things starting making a line on my console...like this:

 

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 

But all in red.

 

Does anyone know what this means and/or how I can get rid of it? Thanks!
