Reload Realtime Command Syntax

Hello!

When Staffan was walking us through 1.6, he showed us the ability of Uniview to "reload" an object and the shaders for Uniview without restarting the program via a command in the custom commands window.

I hadn't needed to use it in the intervening time and have forgotten the syntax. Would it be possible to post this? It would make it much faster to work with 3D models.
