interfere with the systemwide
shortcut for invoking
Spotlight. You can change it

and descender in the window. Zoom to Actual Size (Cmd-Optzero)
will zoom one font unit to the size of one screen pixel.
Or you can use the zoom buttons in the bottom right corner
of the window. Alternatively, you can set the zoom value
numerically by entering a point height in the field between
the buttons. The value specifies at which size 1000 units will
be displayed. Since Mac OS X assumes a screen resolution of
72 ppi, one point corresponds to one actual screen pixel, so if
you enter a value of 1000, one unit will zoom to one pixel.
2.4.2 Panning
You can use trackpad panning gestures. Use the wheel of
your mouse to scroll vertically, hold down shift to scroll
horizontally.
Alternatively, you can switch to the Hand tool
(shortcut H) and drag the canvas around, or simply hold down
the space bar to temporarily switch to the Hand tool. If you
are in text mode, simply pressing the space bar would add
a word space to your sample text. To avoid that, press Cmd-
Space and subsequently release the command key.
2.4.3 Nodes in Alignment Zones
Nodes located exactly on a vertical metric line (see the Font
Info chapter for further details) are highlighted with a beige
diamond. Inside an alignment zone (see 6.2, ‘Masters’, p. 55),
the highlighting assumes the shape of a circle. This helps
controlling the position of nodes even at small zoom scales.
