Enable Caret Browsing on Chromium-Based Edge. To get started, download the latest version of Edge Canary. On the address bar of Edge Canary, enter edge://flags. You can then call SetCaretPos to set the current position of the caret and ShowCaret to make the caret visible. The system sends the WMSETFOCUS message to the window receiving keyboard focus; therefore, an application should create and display the caret while processing this message.

This section has code samples for the following tasks:
Creating and Displaying a Caret
Upon receiving the keyboard focus, the window should create and display the caret. Use the CreateCaret function to create a caret in the given window. You can then call SetCaretPos to set the current position of the caret and ShowCaret to make the caret visible.
The system sends the WM_SETFOCUS message to the window receiving keyboard focus; therefore, an application should create and display the caret while processing this message.
To create a caret based on a bitmap, you must specify a bitmap handle when using CreateCaret. You can use a graphics application to create the bitmap and a resource compiler to add the bitmap to your application's resources. Your application can then use the LoadBitmap function to load the bitmap handle. For example, you could replace the CreateCaret line in the preceding example with the following lines to create a bitmap caret.
Alternatively, you can use the CreateBitmap or CreateDIBitmap function to retrieve the handle of the caret bitmap. For more information about bitmaps, see Bitmaps.
If your application specifies a bitmap handle, CreateCaret ignores the width and height parameters. The bitmap defines the size of the caret.
Hiding a Caret
Whenever your application redraws a screen while processing a message other than WM_PAINT, it must make the caret invisible by using the HideCaret function. When your application is finished drawing, redisplay the caret by using the ShowCaret function. If your application processes the WM_PAINT message, it is not necessary to hide and redisplay the caret, because this function does this automatically.
The following code sample shows how to have your application hide the caret while drawing a character on the screen and while processing the WM_CHAR message.
If your application calls the HideCaret function several times without calling ShowCaret, the caret will not be displayed until the application also calls ShowCaret the same number of times.
Destroying a Caret
When a window loses the keyboard focus, the system sends the WM_KILLFOCUS message to the window. Your application should destroy the caret while processing this message by using the DestroyCaret function. The following code shows how to destroy a caret in a window that no longer has the keyboard focus.
Adjusting the Blink Time
2+1 Film
In 16-bit Windows, a Windows-based application could call the GetCaretBlinkTime function to save the current blink time, then call the SetCaretBlinkTime function to adjust the blink time during its processing of the WM_SETFOCUS message. The application would restore the saved blink time for the use of other applications by calling SetCaretBlinkTime during its processing of the WM_KILLFOCUS message. However, this technique does not work in multithreaded environments. Specifically, the deactivation of one application is not synchronized with the activation of another application, so that if one application hangs, another application can still be activated.

Applications should respect the blink time chosen by the user. The SetCaretBlinkTime function should only be called by an application that allows the user to set the blink time.
Processing Keyboard Input
The following example demonstrates how to use a caret in a simple text editor. The example updates the caret position as the user types printable characters and uses various keys to move through the client area.
