All global variables are always accessible from your channel so you just look for it like any channel variable.  If you set a var with the same name on the channel, it will mask the global.
 
You can also use ${global_getvar <varname} but really there is little point when you can use ${<varname>} as usual.

Perhaps you want limit, hash, or DB. Those are accessible by name from everywhere.

Although, I think there are globals too somewhere.
