Hi Vamsi,
You can use the keyboard callbacks to read keystrokes in your UI Figure. Specifically, the "KeyPressFcn" and "KeyReleaseFcn" functions are designed to be activated upon the respective events of a key press and key release within the UI figure or its child components.
Refer the following documentation for more information:

Best,
Umang
