+dmenu is a generic menu for X, originally designed for
 .BR dwm (1).
 It manages huge amounts (up to 10.000 and more) of user defined menu items
 efficiently.
 .SS Options
 .TP
+.B \-font <name>
+defines the font.
+.TP
+.B \-normbg <color>
+defines the normal background color (#RGB, #RRGGBB, and color names are supported).
+.TP
+.B \-normfg <color>
+defines the normal foreground color (#RGB, #RRGGBB, and color names are supported).
+.TP
+.B \-selbg <color>
+defines the selected background color (#RGB, #RRGGBB, and color names are supported).
+.TP
+.B \-selfg <color>
+defines the selected foreground color (#RGB, #RRGGBB, and color names are supported).
+.TP
+.B \-t <seconds>
+defines the seconds to wait for standard input, before exiting (default is 3).
+.TP
 .B \-v
 prints version information to standard output, then exits.
 .SH USAGE
-.B dmenu
-reads a list of newline-separated items from standard input and creates a menu.
-When the user selects an item or enters any text and presses Return, his choice
-is printed to standard output and
-.B dmenu
-terminates.
-.B dmenu
-is completely controlled by the keyboard.  The following keys are recognized:

 .TP
-Left/Right
+.B Left/Right
 Select the previous/next item.
 .TP
-Tab
+.B Tab
 Copy the selected item to the input field.
 .TP
-Return
-Confirm selection and quit (print the selected item to standard output).
+.B Return
+Confirm selection and quit (print the selected item to standard output). Returns
+.B 0
+on termination.
 .TP
-Shift-Return
+.B Shift-Return
 Confirm selection and quit (print the text in the input field to standard output).
+Returns
+.B 0
+on termination.
 .TP
-Escape
-Quit without selecting an item.
+.B Escape
+Quit without selecting an item. Returns
+.B 1
+on termination.
 .TP
-Backspace (Control-h)
+.B Backspace (Control-h)
 Remove enough characters from the input field to change its filtering effect.
 .TP
-Control-u
+.B Control-u
 Remove all characters from the input field.
-.P
-.B dmenu
-returns
-.B 0
-if Return is pressed on termination,
-.B 1
-if Escape is pressed.
-.SH CUSTOMIZATION
-.B dmenu
-is customized by creating a custom config.h and (re)compiling the source
-code. This keeps it fast, secure and simple.
