How to close tab in tmux?

Question

Is there a shortcut key to close a tab?
I'm asking for something like creating a tab CTRL b + c
What shortcut should I use if I would like to close the 1:cmatrix* tab?

Answer 1

I think this is what you are looking for: http://www.dayid.org/os/notes/tm.html

Specifically this part:

kill the current pane: ^b x OR (logout/^D)  
close other panes except the current one: ^b !  

The formatting here is simple enough to understand (I would hope). 
^ means ctrl+, so ^x is ctrl+x. M- means meta (generally left-alt or escape)+,
so M-x is left-alt+x
