Question about Free Company's Tag

Hi there, I started playing this (amazing :o) game last week, and I've got a simple question about FC's tag.

When I use the little menu on the right side of the screen in order to then open the FC panel, just next to "Free Company", it appears something like "[GRAVE]". I just don't know where did that come from, as my FC's tag is not that one; I don't even know what that thing means, and any info about that would be appreciated.

Thanks in advance and sry for my English, it's not my first language :).

In the menu, whatever appears in brackets is the hotkey for that menu item. If it says

Free Company [GRAVE]

then you can open the free company window directly by pressing your grave key. If you'd like to change this, you can use the keybind interface (System menu > Keybind, or type /keybind in your chat box).

Oh, I didn't even know that key's name, that clears everything. Thanks a lot :).
