ISeleniumKeyUpNative Method WebDriver
Simulates a user releasing a key by sending a native operating system keystroke. This function uses the java.awt.Robot class to send a keystroke; this more accurately simulates typing a key on the keyboard. It does not honor settings from the shiftKeyDown, controlKeyDown, altKeyDown and metaKeyDown commands, and does not target any particular HTML element. To send a keystroke to a particular element, focus on the element first before running this command.
