Environment: Windows 7, MS Office 2007, OpenOffice
In the Control Panel->Fonts section, there are a number of fonts available, sometimes as families. For example, the Arial family (double click on it) shows both Arial and Arial Narrow. The Arial one has a few different versions, like "Arial Bold" and "Arial Bold Italic" and "Arial Italic". The Cambria font is the similar.
When, if at all, are these Bold, Italic, etc. versions of these fonts ever used? In MS Office and OpenOffice they they are not available to choose from.
Any insights on if I even need to keep them on my system at all?
