Command Syntax	Action
{VKEY X}	Sends the VKEY of value X. For example, {VKEY 13} is equivalent to VK_RETURN.
{BEEP X Y}}	Beeps with a frequency of X and a duration of Y milliseconds.
{DELAY X}	Delays sending the next key of X milliseconds. After the delaying the following key, the subsequent keys will not be further delayed unless there is a default delay value (see DELAY=X). Example: {DELAY 1000} <-- delays subsequent key stroke for 1 second.
{DELAY=X}	Sets the default delay value to X milliseconds. This will cause every key to be delayed X ms. If a value is already set and you specify {DELAY Y} you will have your following key delay Y ms but the subsequent keys will be delayed X ms.   Example: {DELAY=1000} <-- all subsequent keys will be delayed for 1 second.
{APPACTIVATE WindowTitle}	Activates an application using is WindowTitle. Very useful if you want to send different keys to different applications.
