HTML Content Viewer doesn't have the shortcut key like applet CV, e.g. Shortcut to jump to the corresponding document F1-F4, CTRL 1-9, CTRL Scroll to zoom in/out.
Suggesting when we are pressing the Alt+K, should make a prompt to display like "Object Key is copied to clipboard" or like "CRDA(2025-xx-xx-xx.xx.xxxxx is copied to the clipboard"
