  Well, since you have already climbed into this section, then
This means you've figured out the controls a little.
More specifically, boom control simultaneously
Exactly from Kempston, Keyboard:
Q/S+A/X+O+P+SP/M, Sinclair 2.             
                                          
  Features of control in the leaflet: when
moving the cursor over the left edge of the screen,
then a wretched menu appears, in which
that only X is the way out. Do the same
can be done by pressing BREAK or EDIT.               
                                          
<-= Here.                                 
                                          
  Features in the menu: windows can be moved
walk, grabbing the title line;
the windows close if you click on X; maybe
but look BACKGROUND if in the main
click on _ in the window.                    
                                          
  Well that's all... for now... until others
times...maybe...or maybe not
be... :))))))))))
