Zoom In and Zoom Out Shortcuts

Some web documents are set in such small text (font) size that even with healthy eyes it's quite a strain to read them.

A quick way to enlarge the text is to use Zoom In shortcut:

Command+

To make the text smaller type Command- (minus)

This shortcut also works in Preview – very useful for reading PDF documents, books for example, that are typeset in too small font size.
