Custom Alias

Good afternoon,

 

i have created a custom command in Customize Interface>>commands and now i would like to assign it to a character on the keyboard, i have been to user preferences>>aliases and changed the alias "G" but what am i supposed to put in the command section? i've tried the command ID with _ & - options  and also the command name copy and pasted from customize interface but all i get is Unrecognized command returned from the CMD window?

 

Your Help Will Be Greatly Appreciated,

 

Cheers,

 

Dan
