Each input event is represented by a cons cell containing two integers, and these integers encode the event. The encoding is opaque; the only way to access an event meaningfully is via the functions provided.
Each event has a string representation, called its "name". Names
consist of zero or more modifiers, followed by a key or mouse action
indicator. Modifiers are separated from succeeding elements by
hyphens -. For example, hitting <x> while holding down the
<Control> and <Meta> keys would generate an event named
<Control-Meta-x>. This notation is designed to closely match
Emacs Lisp's notation.
Functions are available to convert between the name of an event and the actual event itself, and vice versa.
| lookup-event event-name | Function |
Create and return a new input event whose name is event-name.
(lookup-event "C-x")
=> (120 . 65540)
(lookup-event "C-M-Button1-Click1")
=> (1 . 131340)

| event-name event | Function |
This function returns a string naming the input event event.
