#PSTip Tab Completion in PowerShell 3.0
Note: This tip requires PowerShell 3.0 or above.
PowerShell’s tab completion just got better in v3. In addition to all its awesomeness, it is now capable of completing service or process names, event log names, module names and the list is long.
# event logs PS> Get-EventLog -LogName # services PS> Get-Service -Name # processes PS> Get-Process -Name

Note that, in the ISE, you might need to press Ctrl+Space right after the opening brace to invoke Intellisense.
