If you’re reviewing some PowerShell code loaded into the PowerShell ISE, it’s really simple to get additional information. Click the cmdlet you want to know more about, then press CTRL+SPACE.
This invokes the intelliSense menu that typically opens on the trigger keys “-“ and “.”. Since only one cmdlet matches, the list has just one item, and a split second later, a tooltip shows all the parameters supported by this cmdlet.
If you’re hungry for more, press F1. PowerShell ISE now takes the cmdlet name your caret is in, and runs the Get-Help command on it. Help opens in a separate new window.
