Breath FX macro question

I'm trying to setup an fx for a breath weapon and I currently have this one. /fx breath-fire @{selected|token_id} @{target|token_id} Which is great if there is a target token in the center of where I want the cone to go but is there a command to taget a space instead of token_id?  Thanks for the help.

Nevermind I figured it out.  I added  /fx breath-fire  at the end of the breath weapon macro and it automatically uses the token as the starting point and I can click anywhere for the end point.   FYI  /fx beam-fire @{selected|token_id} @{target|token_id}  is good for firebolt.  I was just overthinking things when trying to make it work for fire breath.
