Incidentally, if you forget which icon does what, you can always find a menu item that does the same thing but it is identified in plain English instead of an icon.

The properties dialog box can be opened from the main menu View \ Properties. The main menu, in all windows programs, is the top menu on any program window.

Also, in any windows program, you can be spared the "icon maze" as I call it, by using the main menu options which do the same thing as the icons, only with written options.
