Tip of the day: using wildcards in UIAutomation

One of amazing features of PowerShell cmdlets is supporting so-called wildcards. What are wildcards? The characters that substitute one or more, or even all of the characters in the string.
For example, you need to simplify your code:

Start-Process calc -PassThru | Get-UIAWindow | Get-UIAButton -Name a* | Invoke-UIAButtonClick;

This code presses the plus button, the button that is named Add.
Imagine that you need to press the Reciprocal button and you’ll immediately love wildcards.
