Expression Tab in Graph Editor

[PGuilherme]

Hi! Quick and possibly dumb question:
I'm using AE and, I don't know why, actually openned a expression tab inside my graph editor window. It doesn't block me out from working or nothing, but in my case, I'm not using a very large monitor, which costs me a nice portion of the screen haha....
Do you guys know any hotkey or icon to close it?
Thanks!

Check the icons at the bottom of the graph editor. The two leftmost control visibility and display options, including toggling the expression editor.
