There are a multitude of ways to open the properties dialog. The most obvious is to select an element and click the Properties Button. Of course you can use the Edit menu > Properties. Doing that should make you aware of the "PR" keyboard shortcut (stock shortcuts).
If you are a "Right Clicker"...then you can choose Element Properties from the list, it's the one all the way at the bottom. Don't be fooled into thinking that View Properties is what you want, "View" in this case isn't a verb.
A couple less obvious items are to use Windows Keyboard shortcut combinations, and there are a lot. I find that I just can't remember enough of them which means looking them up counters their effectiveness. Unless you can manage to replace something else you want to remember with some new ones?
You can use this combination, Alt+Enter to edit the Element properties of your current selection. Once open this combination, Ctrl+Enter will toggle back and forth between the Element and Type properties dialogs.
I should also mention that there is always the ALT key plus menu letters combinations. Depending on your Windows settings pressing the ALT key should display little underlined letters in the menu. Pressing ALT then the underlined letter will expand that menu and then you can do the same for the next level until you get where you want to go.
For properties it would go something like this: select something
Press ALT, press E, press I (twice because I is shared with Resize and Properties)
Press Enter, Press E to open Type Properties dialog.
It is actually much quicker than it looks but no, I'm not suggesting it is faster than just typing PR (keyboard shortcut).
