You can also do something like :
noremap XX :set hlsearch!<cr>:set hlsearch?<cr>

And take a look at http://vim.sourceforge.net/scripts/script.php?script_id=48 for more complex toggle actions.

I think the simplest way to do this is :noremap XX :set invhlsearch<CR>

For options which have only "on" or "off" settings, giving the 'inv' prefix to the option causes it to be toggled.

The "inv" prefix only works with versions 6.x of VIM. It seems to do strictly the same
thing '!' does. But it does not echoes the value of the option.

Hence, 'set option?<cr>' is still useful if you want to know its new current state.
