NAME
       dasher - graphical predictive text entry system

SYNOPSIS
       dasher [OPTIONS] [filename]

DESCRIPTION
       Dasher is an information-efficient text-entry interface, driven by nat‐
       ural continuous pointing gestures. Dasher is a  competitive  text-entry
       system wherever a full-size keyboard cannot be used.

OPTIONS
       dasher takes the following options:

       -a, --appstyle=STYLE
	      Application  style.   STYLE  can	be any of traditional, direct,
	      compose, or fullscreen.  The default is whatever	was  specified
	      on the previous invocation of Dasher, or traditional when Dasher
	      is started for the first time.

       -?, --help
	      Describe command line options.

       --help-options
	      Describe the options available with --options.

       -o, --options [option=value[,option=value...]]
	      Override stored options.	Options values are remembered for sub‐
	      sequent invocations of Dasher.

USAGE
       The  main Dasher interface is a window with a blank background contain‐
       ing a column of letters on the right hand side.	Click the mouse button
       to start.  When the pointer is to the right of the crosshair the screen
       will zoom towards the point underneath the mouse pointer.  To select  a
       letter,	move  the  mouse pointer into it and watch how it zooms under‐
       neath the crosshair.  A new column of  letters  will  appear.   Staying
       within  the  box	 for the selected letter, move the pointer over one of
       these letters to select it  as  the  next  letter.   Moving  the	 mouse
       pointer	to the left of the crosshair, or outside of the box for previ‐
       ously selected letters, allows you to change previously	selected  let‐
       ters.

Application Styles
       traditional
	      Dasher displays an edit box above the main window.  Text entered
	      via Dasher will appear in the edit box allowing the text	to  be
	      edited directly.

       direct The  edit	 box  is not displayed.	 Dasher runs without focus and
	      the text goes into whatever window does have  focus.   This  way
	      you can use it more practically to run your desktop.

       fullscreen
	      dasher expands to the entire screen.

MENUS

	      letters to present (for instance,	 a  training  file  containing
	      scientific  terms	 to  add  to  the  initial  English training).
	      Training files must be UTF-8 encoded.

THE PREFERENCES DIALOG
       The preferences dialog is split into several panes.

   Alphabet
       Choose  a  different alphabet. Dasher will automatically retrain itself
       if the alphabet specified training file is present.

   Colour
       Choose a different colour scheme.

   Control
       Alter various control options

       One dimensional mode
	      Map the Y position of the mouse to a 2 dimensional  position  on
	      the Dasher canvas (useful for limited mobility users)

       Eyetracker mode
	      Similar  to one dimensional mode, but behaves normally except at
	      the right-hand side  of  the  canvas.  Designed  for  eyetracker
	      users.

CONVERTING TRAINING FILES TO UTF-8
       Dasher  requires	 that  training	 files be in the UTF-8 format, whereas
       most text files are likely to be in ISO-8859 format. This doesn't  mat‐
       ter for plain text, but accented characters are encoded differently. In
       order to convert them, use the iconv(1) program. For instance, if  your
       training	 file is in ISO-8859-1 format (Western European), run iconv -f
       ISO-8859-1 -t UTF-8 trainingfile >newtrainingfile

FILES
       /usr/share/doc/dasher
	      Directory containing system-wide configuration files.

       ~/.dasher
	      Directory containing user specific configuration files.

       Dasher will utilise files of the following  form	 from  both  of	 these
       directories:

       alphabet.ALPHABET.xml
	      The files defining the alphabets available to Dasher.

       colour.SCHEME.xml
	      The files defining the colour schemes available to Dasher.

       training_LANGUAGE*.txt
	      Files  containing	 the  training data used by Dasher.  These are
	      UTF-8 encoded text and should contain a representative sample of
	      the relevant language.  User specific training files can be used
	      to augment system wide data.

       Refer to the Dasher manual for more information	regarding  the	format
       and editing of these files.
