[XeTeX] Jump symbol in latex

[Yaniv Hollander]

Hello,

I need a help with finding the command that will produce a jump  
symbol in Latex.
A jump symbol looks like this: '[[', ']]'.
Latex provides the command \lVert and \rVert for the symbol '||'. I  
need two left brace and right brace commands the will produce the  
same thing but with '[[' or ']]' instead of '||'.

Thanks,


Yaniv                       Hollander
