Project Description:
There is a textbox with the text "Keywords" in it.
If the user clicks in the textbox, the contents of it should clear.
Currently I have the above working using JavaScript's onclick event.

This is what I need:

If the user then moves focus away from the textbox without having entered something, the text "Keywords" should re-display in the textbox.

Example:

Textbox has "Keywords" written in it.
User click in the textbox and the textbox becomes blank.
The user clicks somewhere else on the screen. The textbox should get re-populated with the text "Keywords".
