I’m reading a book called Learn Powershell in a Month of Lunches by Don Jones and Jeff Hicks and I just discovered a helpful nugget I didn’t know existed,

-ShowWindow parameter will give you a popup window with the help topic you’re researching. You can search words and phrases within the help topic. The found term is highlighted for easy reading and you can move between terms using the previous and next buttons. The window can be resized and you can increase or decrease the text with the slider at the bottom of the window. The description is a bit shorter for some cmdlets, but there are even some command examples displayed in the help window to get you going without coming out of your prompt.
