Control mode

Provides a control node at the bottom of the screen. This allows various tasks to be performed inside Dasher, such as editing the text written, speaking entered text and stopping or pausing Dasher. If compiled with and using a desktop supporting the ATK accessibility framework, compliant applications will have their menu trees exported to Dasher and these may be accessed via this node.

About Dasher

Display information about the current version of Dasher

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

Choose a different colour scheme.

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.

Start on left mouse button

The left mouse button will toggle Dasher between running and paused state

Start on space bar

The space bar will toggle Dasher between running and paused state

Start with mouse position

When paused, Dasher will display a red box. If the pointer is held in the red box until a yellow box appears, and then in the yellow box until it vanishes, Dasher will start. This allows users with no button input to start and stop Dasher.

Copy all on stop

Toggle whether the current text is automatically copied to the clipboard when Dasher is stopped

Speak on stop

Toggle whether the newly entered text should be spoken when Dasher is stopped. Requires --with-speech to have been used during Dasher configuration and building.

Pause outside window

Toggle whether Dasher pauses if the mouse cursor is moved outside the Dasher window

Orientation

Change the relative position of the letters to the crosshairs. Alphabet Default will allow alphabets to set this automatically.

Draw box outlines

Change colour scheme automatically

Alphabets may provide a preferred colour scheme. If this option is enabled, Dasher will automatically change to it.

Smoothing

The greater the smoothing value, the greater the uniformity of the box sizes. This will reduce the predictive capabilities of Dasher, and so may reduce writing speed.

Timestamp new files

Include the time at which a file is saved in the filename

Distance from centreline for start on mouse position

Controls the distance from the centre of the Dasher screen that the mouse position start boxes will appear.

Number of pixels that should cover the entire y range

Controls how many pixels of input should correspond to complete coverage of the Dasher canvas. Only used in one dimensional mode.
