 This plugin implements a screen reader for user interfaces created with the [Godot game engine](https://godotengine.org). The goal is to enable the creation of [audio games](https://en.wikipedia.org/wiki/Audio_game) with Godot, as well as to add accessibility functionality to user interfaces and to encourage the creation of accessible games.

 ## Why?

 If so many developers are flocking to engines like Unity, it must be that they derive some advantage from the platform. But because the Unity development environment isn't accessible, I as a blind developer have no way of knowing whether that style of development would work for me. This addon is my way of exploring those possibilities and, with any luck, of making compelling games of my own.
 
-Anecdotally, I've learned that building games with Godot is not only possible, but is becoming very fast as I refine my workflow. My process probably looks nothing like that of most other Godot users. I use the editor to set up scenes, edit properties, etc. Then I drop to a shell prompt, edit the _.tscn_ files by hand, then run the game from the shell. The editor is more of an exploratory interface for the work I mostly do by hand, and has been invaluable at helping me discover property and signal values without pouring through pages of documentation for multiple classes. But even though this approach is a bit more obtuse than just picking a scripting language, what I get from Godot is a set of components that can perform just about any game-related task I need. I also can export games to just about any platform--Windows, Linux, MacOS, Android, iOS, and UWP for the Xbox One.

 `ScreenReader` also customizes keyboard handling to account for the fact that Godot's is somewhat lacking. It attempts to set an initial focus whenever a new scene is initialized so keyboard focus works more often than not.
 
+Further, `ScreenReader` automatically intercepts all touchscreen interactions to emulate basic explore-by-touch and swipe navigation as found on Android and iOS. Currently, left and right swipes emulate _Tab_ and _Shift-tab_. The touchscreen can also be explored, and a double-tap anywhere triggers the last item to gain focus.

 ### Editor accessibility
 
-Since the Godot editor is itself a Godot UI, the plugin optionally injects a `ScreenReader` node into the editor. The interface isn't accessible enough to create games entirely from within the editor, but games can still be created by using Godot's editor to get an idea for how files should be structured, then editing them by hand in a more accessible IDE.

Please install a GitHub release, since the version in the marketplace doesn't seem to work with Godot 3.2.

 This often happens if I run a game from within the editor, then exit the game. Focus seems to land somewhere outside of a control and can't be restored, and my defensive code doesn't kick in.

 There's no keyboard-equivalent for this, but fortunately the addon has your back. Use the _Application_ key as you normally would. Note that this key performs a right-click. I can't guarantee that will always open a context menu, but it does just that for the scene tree and other nodes with documented context menus.
