 ### Features
 
-* **Cross Platform** - Works on Windows, Mac, and Linux. Terminal drivers for Curses, [Windows Console](https://github.com/migueldeicaza/gui.cs/issues/27), and the .NET Console mean **Terminal.Gui** works well on both color and monochrome terminals and has mouse support on terminal emulators that support it.
-* **Keyboard and Mouse Input** - Both keyboard and mouse input are supported, including limited support for drag & drop.
-* **[Flexible Layout](https://migueldeicaza.github.io/gui.cs/articles/overview.html#layout)** - **Terminal.Gui** supports both *Absolute layout* and an innovative UI layout system referred to as *Computed Layout*. *Computed Layout* makes it easy to layout controls relative to each other and enables dynamic console GUIs.

 * **[Arbitrary Views](https://migueldeicaza.github.io/gui.cs/api/Terminal.Gui/Terminal.Gui.View.html)** - All visible UI elements are subclasses of the `View` class, and these in turn can contain an arbitrary number of sub-views.

 ### Keyboard Input Handling
 
+**Terminal.Gui** respects common Linux, Mac, and Windows keyboard idioms. For example, clipboard operations use the familiar `Control/Command-C, X, V` model. `CTRL-Q` is used for exiting views (and apps).
+
 The input handling of **Terminal.Gui** is similar in some ways to Emacs and the Midnight Commander, so you can expect some of the special key combinations to be active.
 
 The key `ESC` can act as an Alt modifier (or Meta in Emacs parlance), to allow input on terminals that do not have an alt key. So to produce the sequence `Alt-F`, you can press either `Alt-F`, or `ESC` followed by the key `F`.
@@ -66,25 +66,9 @@ To enter the key `ESC`, you can either press `ESC` and wait 100 milliseconds, or
 
 `ESC-0`, and `ESC-1` through `ESC-9` have a special meaning, they map to `F10`, and `F1` to `F9` respectively.

-
-`CTRL-Q` is used for exiting views (and apps).
-
-**Terminal.Gui** supports rebinding keys. For example the default key for activating a button is Enter. You can change this using the `ClearKeybinding` and `AddKeybinding` methods:
-
-```csharp
-var btn = new Button ("Press Me");
-btn.ClearKeybinding (Command.Accept);
-btn.AddKeyBinding (Key.b, Command.Accept);
-```
-
-The `Command` enum lists generic operations that are implemented by views. For example `Command.Accept` in a Button results in the `Clicked` event firing while in `TableView` it is bound to `CellActivated`. Not all commands are implemented by all views (e.g. you cannot scroll in a Button). To see which commands are implemented by a View you can use the `GetSupportedCommands()` method.
-
-Not all controls have the same key bound for a given command, for example `Command.Accept` defaults to `Key.Enter` in a `Button` but defaults to `Key.Space` in `RadioGroup`.
+Apps can change key bindings using the `AddKeyBinding` API. 
 
-Keybindings only operate while a view has focus. To register global hotkeys you can override a view's `bool ProcessHotKey (KeyEvent kb)` method.
