The key property enumerates a collection of methods to send keystrokes to the host screen by Javascript.
These methods are associated to the underlying terminal type, and each one represents a different keystroke.
The following example shows how to send ENTER ('@E'):
hs.key.enter();
The following table lists the complete keystroke collection for 3270 and 5250 terminals, with the HLLAPI squence depending on the terminal type:
