IntelliSense is an invaluable resource while coding. It provides information about available members of a type and displays parameter details for different method overloads. You can also use IntelliSense to complete a word once you have typed enough characters to make it unambiguous.
As you type, IntelliSense displays Quick Info about the query symbol.
To insert the rest of the word query using IntelliSense's word completion feature, press Tab.
