scroll_delay
Controls the speed of the scroll by specifying the delay, in milliseconds, between each update of the weblet.
To avoid overloading the client CPU, the browser will automatically round any value less than 60 milliseconds up to 60. The parameter can be used with Internet Explorer to override this behaviour and honor the specified scroll_delay.
Default Value
Blank. This allows the browser to set it's own default. The default may vary slightly between browsers but should be around 85 milliseconds.
Valid Values
Any integer value.
