 Typographic Conventions
------------------------------------------------------------------------------

     This guide employs several typographic conventions:

 Key Names

     The names of keys, such as Enter, Ctrl, and Del, appear in the document
     as they do on your keyboard, where possible.

     Note that when referring to the four arrow keys on your keyboard as a
     group, they are referred to as Direction keys; however, the name of each
     Direction key is used when referring to them individually.

 Key Combinations

     Whenever two keys are joined together with a plus (+) sign (for example,
     Ctrl+R), you should hold down the first key while pressing the second
     key to complete the command.  Release the second key first.

 Key Sequences

     When keys are separated by a comma (,), press them in the sequence
     indicated.  The keystroke command Alt+E,C, for example, indicates that
     you should hold the Alt key down while pressing the E key, release them
     both, and then press and release the C key.
