When in doubt, check the menus...


I don't like the notation for this pair. > and < are both 'upper case' characters, and require the shift key, as well as the command key. I'd prefer to see it included in the description, as is done for Show/Hide Layout, Show/Hide Invisibles, etc. That's also true for the command - {, command - |, and command - } combinations used for left, center, and right alignment of text in selected paragraphs. Without shift included, you get command - [, command - \ and command - ], KB shortcuts for decrease indent, nothing, and increase indent.
Bottom line: (shift -) command - > and (shift -) command - < zoom the page, with shift included in the keystroke combination whether or not it's included in the notation.
command - < (without pressing shift) is command - , and opens the application's Preferences dialogue.
command - > (without pressing shift) is command - . Prior to OS X, this stopped the current routine, providing an escape route from a process that was running in circles. In OS X it sounds a beep, but does nothing beyond that.
command - - (command - hyphen) decreases the size of the selected text (by one point).
command - + (command - plus) increases the size of the selected text (by one point).
Both of these work with the shift key included or omitted.
