Apparently I wasn't understood correctly by you.

I wrote that the controller system understands only keyboard shortcuts (and mouse clicks) to program the device.

For example, Alt + F1 (Cntrl + G) and so on.
But not the format of the script type moi (script: var vp = moi.ui.mainWindow.viewpanel.getViewport('3D'); if ( vp.projection == 'Perspective' ) { vp.projection = 'Parallel'; } else { vp.projection = 'Perspective'; })
