I'm pretty sure it's me screwing something up, but for the life of me, I can't figure out what!

Running MUSHclient, and trying to set up my old aliases I used to use in zmud

Alias: invis *
Command: c invis %1
Send To: World

(NOTE: In zmud, I never put the star, just invis, then the program picked up the extra with the %1)

Now, here's where the problem comes in. If I type "invis whatshisname", then the alias fires correctly and sends "c invis whatshisname". HOWEVER, if I just type invis, then the alias sends "invis", and I get back a "huh?". Is there a way to have an optional wildcard so for spells like word or invis I can type the target if there is one, or just leave it off and have it fire at me? Hope that makes sense, I'm tired...
