If I am in the Image Popup section, and I select inside the text box for URL, I can single click inside the text box then drag my cursor to select the text in the box. If I try the same process in Title, Caption, or Link, I cannot single click in the box and drag to select at all. I have to Ctrl A to select the text for all, but if I want to select to drag to remove a few characters, I need to use two hands with Select and Shift to Select a few characters. I would like the same User experience of URL for all the text boxes. One handed, Single click and drag to select.
