How to select multiple widgets with mouse cursor when they are overlapped?

Hi Everyone,

Like the title said, I have the check the keyboard-shortcuts and CAN NOT find the way select the 3 Text boxes( images at below) with mouse-cursor. Instead, I can only select these three with Shift+Click which seems lack of efficiency.

Any tips I have missing?

Thanks in advance.

Click the “OUTLINE” tab to view all the widgets on the page, then use your mouse cursor to click on an individual widget name

I was expecting that maybe I can hold some magic key to select them by draw a rectangle
with mouse cursor.
