Looking Out Cab View?

Can anyone please help out: I can’t seem to find a keyboard shortcut for the looking out left and right cab windows. The only way I can see to do this is through the F4 HUD, but it’s a pain to have to change just for that.

Arrow keys/right mouse click just change the view inside the cab.

Cheers...

 

You mean you found out by RTFM

 

Many thanks. I did reread the manuals I have prior to posting, but couldn’t find it.
