Using raven screen as if it was a regular screen

My apologies if this has been covered elsewhere, it must be addressed somewhere but I couldn't see it on the forum or videos:

I would like to use the Raven MTI2 without having a separate screen for my computer.

Can I ask:


1.  Is there a way to jump out of 'Raven' mode and into 'normal computer screen' mode?  
2.  Is it possible to use the mouse on the Raven rather than use the touchscreen?
3.  Is it possible to use regular hot key commands for example command+= to switch the raven from mix to edit window?
4.  Will the raven still work with a 4k display-style computer for example the new power iMacs?

Many thx
