Key Sequences

A key sequence string is a comma-delimited set of key identifiers which are used to simulate the key press and release sequence of a standard U.S. 101-key AT-style keyboard.

If a key identifier appears in the string without a preceding modifier, a key-pressed code is simulated, followed immediately by its corresponding key-released code. Key modifiers can be used to change this behavior.

For example, the DOWN modifier will send the key-pressed code for the following key identifier without sending the key-released code. This is useful for simulating Ctrl, Alt, and Shift keys when they are held down while other keys are being sent. To release the key, it must be included in the key string again along with a preceding UP modifier.
