These are two quick hacks.  Both are based on the hotkey technique of
POPCLI.  BIG is used to magnify the screen.  Run it from CLI or WORKBENCH.
Put the mouse cursor near the part of the screen you want to magnify and
hit LEFT-AMIGA/HELP together.  The quarter of the screen around the cursor
will be magnified 2 times.  Hit any mouse button to return to the normal
display.  If the mouse cursor is in the absolute upper left corner of the
screen before LEFT-AMIGA/HELP is pressed, BIG will clean up and exit.

NW moves the current window to the back and activates the next window
when the key sequence LEFT-AMIGA/z is hit togther.
If there are no more windows on the current screen, the next screen
is brought forward and its first window activated.  After the last
window on the last screen is displayed, the first window on the first
screen in broght forward and activated.  As with BIG, if the mouse cursor
is in the absolute upper left corner of the
screen before LEFT-AMIGA/z is pressed, NW will clean up and exit.
