View as a Popup:
To view the essential dignities of a given planet or point, just hover the mouse over the object on your screen. A hint will pop up showing the exact position of that planet or point in that sign and what planets have taken up the essential dignities of that object.
The same information will show in the statusbar at the bottom of the view chart window:
The difference is that the information in the status bar will stay as long as your mouse is over the object on the screen, whereas the popup hint disappears after a few seconds.
