Use the Tab Key

Instead of typing a full cmdlet name, begin typing the first few letters after the action verb and press the Tab key. The Management Shell automatically cycles through the cmdlets that match the string already entered. For example, typing Get-CsP and then pressing Tab automatically changes the string to Get-CsPinPolicy. Pressing Tab again changes it to Get-CsPool. Use Tab to go forward through the list and press Shift+Tab to cycle backward. The Tab key can also autocomplete parameters inside the cmdlet, so it is handy when recalling the exact parameter name. If the tab complete feature is not working it probably means the command is already misspelled and no match can be found.
