Chord Overview and Editing Page

Gesture Overview

There are two ways to view the contents of a chord:  expand its node in the gesture tree, producing a vertical list of its gestures, or select it to see the chord edit page. The chord edit page shows the gestures as buttons arranged roughly according to direction of motion.  On each button you will see an icon for the direction of motion, the gesture name and gesture hotkeys for the OS mode currently active in the Feature Selector.  Clicking a gesture's button will take you to the event edit page for that gesture.  Use the 'Back' tree-navigation button (w/green left-arrow icon) to get back to the chord overview from the event editor.

Gesture Types

The majority of chord gestures involve sliding motions.  However, there is one SyncTap gesture available for each chord, as well as a TimeDown gesture and BeginSlide/LiftSlide events that can be associated with each chord.  The table below summarizes these gesture types.  Not every chord will allow all gesture types to be mapped.  For instance, hand scaling or rotation gestures are only recognized for chords that include the thumb. And most modifier chords only allow the SyncTap gesture to be mapped.

Typical Usage
SyncTap
SyncTap (ChordTap) -- simultaneous tap of multiple fingers.
Mouse Clicks and Modifier Chords, Enter or Escape
{...
ChordHold -- events that prefix any slide motion events at the beginning of the slide, or if fingers have been held stationary a half second.
For sustaining a mouse button or modifier key (e.g. Alt or Space) throughout multi-finger slides until hand lifts. Generated at the beginning of any slide gesture, but not in response to Chord Tap gestures.
...}
ChordLift -- events to be activated as hand lifts at end of slide.
For releasing any buttons or modifiers pressed by ChordHold events.

Gesture Addition

To add a slide in a new direction (e.g. diagonal), just click the icon in the toolbar at the bottom of the page, and an empty button for that direction should appear.  The gesture addition toolbar only shows slide directions that can be added without conflicting with the chord's existing gestures.  

Gesture Removal

To remove a slide or other action from the chord, just drag its button onto the trash can and release.  The button should disappear.  After removing all gestures along a motion axis (say horizontal or vertical), the gesture addition toolbar will show more options for new gesture directions.

Restoring Defaults

If you click the 'Defaults' button, the original arrangement of gestures for the selected chord will be restored.  

Enabling isolated modifier chord taps to activate Windows Start Menu, etc.

The chord edit pane for modifier chords shows only the SyncTap gesture at the center.
However, at the bottom of the page is a checkbox labeled

 X Ignore modifier chord keystroke if no opposite hand activity.

This checkbox determines whether an isolated tap of the modifier chord, without striking another key on the opposite hand, will generate the modifier keystroke. For instance, if you want to be able to popup the Windows Start menu by tapping the T3F spread chord, you should uncheck this box. But if you're afraid of accidentally touching this chord and popping up the Start menu, check this box for the T3F spread chord. This also applies to the Shift, Ctrl, Alt, and AltGr modifier chords, whose default settings for this checkbox may vary.
