Hi DesuDeus, yup like Pilou says above the actual command name for that is PlanarSrf.

There's a list of all the exact command names in the shortcut keys section of the help file here:

In the future at some point I want to make these easier to set up, like being able to pick the name off of a dropdown list or something like that.

Happy 2011 !
