<p>Pressing the button on the left side of the node allows a message on a topic
to be injected into the flow.</p>
<p>The payload defaults to the current time in millisecs since 1970, but can
also be set to various other javascript types.</p>
<p>The repeat function allows the payload to be sent on the required schedule.</p>
<p>The <i>Inject once at start</i> option actually waits a short interval before firing
to give other nodes a chance to instantiate properly.</p>
<p>The <i>Flow</i> and <i>Global</i> options allow one to inject a flow or global
context value.
</p>
<p><b>Note: </b>"Interval between times" and "at a specific time" uses cron.
This means that 20 minutes will be at the next hour, 20 minutes past and
40 minutes past - not in 20 minutes time. If you want every 20 minutes
from now - use the "interval" option.</p>
<p><b>Note: </b>all string input is escaped. To add a carriage return to a string
you should use a following function.</p>
