VisualSP is incorporated into the SharePoint ribbon interface through the Help tab.
Click the Help tab to expose the help items that are available for the current context in which you are working. Click on an item to view it.
A dialog box will open displaying the help item you selected. In some cases, a new window may open. When you are finished, close the dialog box or window to return to the page.
You can click on the Pop Out link in the lower right-hand corner to open the dialog in a new window. This is helpful if you want to make things bigger or move it to the side so you can refer back to it as you work.
