Choose the way you want the alert box to be removed. If it is "remove" you can't use "TAB" key to show it again. The key "TAB" only works for "hide".

You can define your own color "#333333" or use the color already pre-defined "gray" "green" "red".

You can select how many times you want the alert box to show up. For example if it is number; Jdesc will use cookies to check, either you refresh or close browser and open it again, after 3 times the alertbox will not show up anymore.
