Simple I'm sure but how the F***

I open up internxt explorer. In its url windows there is a URL. WOuld like to select it and then delete it.

After that I would like to type in my own URL, which is straight forward.

But how on earth do I delete the existing URL first, so I don't just type on top of whats already in the URL window.??

Why open IE when you can use the Chromium embedded framework and use an open step to start the browser session. I've added a guard around it to look for an existing open window.

Thx. Appreciate it. I am still very new and 'green'. 
I will go with your solution and take it from there.
