-To set a key, use the form variable=value, where variable is the key and
-value is the value to set it to.  If the value contains quotes or characters
+.IR  variable = value
+To set a key, use the form
+.IR  variable = value
+where
+.I variable
+is the key and
+.I value
+is the value to set it to.  If the value contains quotes or characters
 which are parsed by the shell, you may need to enclose the value in double
-quotes.  This requires the -w parameter to use.
+quotes.  This requires the
+.B \-w
+parameter to use.
 .TP
-.B "-n"
+.B \-n
 Use this option to disable printing of the key name when printing values.
 .TP
-.B "-e"
+.B \-e
 Use this option to ignore errors about unknown keys.
 .TP
-.B "-N"
+.B \-N
 Use this option to only print the names. It may be useful with shells that

 .TP
-.B "-q"
+.B \-q
 Use this option to not display the values set to stdout.
 .TP

+.B \-w
 Use this option when you want to change a sysctl setting.

+.B \-a
 Display all values currently available.
 .TP
-.B "-A"
+.B \-A
 Display all values currently available in table form.
