Reply To: Resize selected line height / spacing

The best way to do this is to use the keyboard shortcuts. For example, select the text and press command-shift-. (period/dot). That will increase all text by 2 points. If you want it to change by a diferent value, you can change this in the Units & Increments pane of the Preferences dialog box.

Another option is to use Blatner Tools (blatnertools.com), which has a panel and keyboard shortcuts that let you change this (and other values, such as indents) much faster than using preferences.
