Today I was heavily working with PowerShell help system. And was tired to call it using Get-Help cmdlet. So I created small function which I put to my profile:

function Show-HelpAboutFunction
{
    $topics = Get-Help about_* 

    foreach ($t in $topics)
    {
        $tn = $t.Name -replace 'about_', 'abt-'
        $text = "function global:$($tn) { Get-Help $($t.Name) }"

        Invoke-Expression "$text"
    }
}

So when in console I can write: abt-func<Tab> and can circulate help topics till have the one I need. I know that for some topics is better to write Get-Help with partial help topic name, but in some cases I like my solution more.

Note: I know that abt is not approved verb :)
