X-SCALING

To change the x-scaling (i.e., to stretch the chemical- shift scale),
type ZO to enter the zoom subroutine. You will get a cursor with
the letters zo at bottom right. Using the mouse, place the cursor at
the left border of the region you want to expand. Click and drag to
highlight the whole region, then right click (shift/click on MAC)
to expand. Type return or enter to go back to the Base Level.
If, from the Base Level, you want to toggle between the full and
expanded spectra, use CTRL-F (MAC and PC) for the full, and CTRL-E
for the expanded version. In an exanded view, you can move right and left
with the small scroll bar at the bottom of the screen.

Move your mouse over the sample spectrum below to watch
the zooming procedure.
