View menu
Zoom Zoom In — Move up to the next closest zoom level, making the canvas appear larger.
Zoom Out — Move down to the next farthest zoom level, making the canvas appear smaller.
Zoom to Actual Size — Move to 100% zoom, so that the canvas appears as large as it actually is according to the canvas units.
Zoom to Selection — Zoom to a level and position that fills the view with the currently selected objects.
Previous Zoom — Return to the last zoom level you had before the current one.
Keep Fit in Window — Zoom to a level and position that keep every object on the canvas visible as you work.
Proof Setup — Use this submenu to set a printing or proofing device and its assigned profile. The default proofing profile is the Mac OS X default proof profile (usually "Generic CMYK Profile"), but you can use the profile of any printing or proofing device available on your system.
Proof Colors — Turn on soft proofing, using the device set in the Proof Setup submenu. This adds an extra step to the display path for images and colors. First each color is converted from the appropriate one of the three document profiles to the proofing profile, then from the proofing profile to the display profile. This theoretically lets you see on screen what your printed output will look like, since it duplicates the printing path in Mac OS X. This does greatly depend upon the quality of the color profile of your printer, though. For many consumer ink jets, for instance, the printer profile claims that it can reproduce any color (as a way to avoid ColorSync and substitute their own color enhancement in the printer driver). For these printers, soft proofing may not visibly change anything.
Extras — There are several things on the canvas (other than the objects themselves) that you might want to see; choose something from this list to show or hide it. Actions — Any object with an action assigned to it in the Action inspector gets an action tag near its upper-right corner.
Grid — This is the grid as defined in the Grid inspector. Note that you can snap to the grid whether it's visible or not.
Guides — These are the manual guides that you set up for aligning objects on the canvas.
Magnets — Choose this to see all objects' magnets, all the time.
Notes — Any object with a note in the Note inspector gets a note tag near its upper-right corner.
Origin — This is the crosshair that represents the canvas origin.
Page Breaks — These are the lines that represent borders between pages.
Rulers — The rulers help you size objects on the canvas, and include an inspector bar for common object editing.
Sidebars — Choose a sidebar's name to show or hide it. The canvases have their own sidebar, while the outline view and the list view share one sidebar.
Outline — the outline sidebar, which shows the hierarchy of objects on the canvas.
List — the list sidebar, which shows the ordering of objects on each layer.
Display Canvas Edit Next Canvas — Switch to the canvas after the one you are currently editing.
Edit Previous Canvas — Switch to the canvas before the one you are currently editing.
Customize Toolbar — Conjure up a sheet of controls that you can drag to your toolbar, like in other Mac OS X applications.
