How to activate the EQ-button ?

[Mark11]

like title says i want that black-golden EQ-button activated. At home at my pc i have it, here on my notebook i don't, no matter what skin i use. I need it because on this button i have the options to activate my horizontal hotkey bars.

I tried my different skins because i thought maybe it shows up then, but that did not happen. Is there a key combination, or what can i do to have it back ?
