Clear contents of text entry field

I have two options.The first secret is that you need to change the entry box, not the associated variable.1. Create transparent button and place over entry field. Create a variable, say _blank, initialized to nothing - empty. Add On Click actions to the button:- Change contents of entry field to _blank- Hide itselfI don't like this one because the user has to click twice. Have not been able to figure out how to get the cursor in the box. Also, does not work if they tab.2. Same as 1 except you use On Mouse Enter. Here the prompt would disappear as soon as the mouse entered and the user would have only one click. Problem here is that if they don't enter anything, the prompt is gone. If you don't care, stop here.2. cont. To get around that, put a second transparent button BEHIND the entry box and just a bit bigger. It would have two On Mouse Enter actions:- Put the prompt in the entry box IF the entry variable is empty. - Show the first transparent button so it will work the next time they enter the field.
