> I want double-tab to print a listing of said options so that I can see them all at once. Is this possible?

In PowerShell 5 (at least in Windows 10), Ctrl-Space yields a list of matching completions. You can then use the arrow keys (ip, down, left, right) to pick one and hit enter or space to select.

It works for commands as well as for options/parameters and parameter values.

I.e. you can type get-pr[ctrl-space] and powershell responds with:

    Get-PrintConfiguration      Get-PrinterDriver           Get-PrinterProperty         Get-Process
    Get-Printer                 Get-PrinterPort             Get-PrintJob                Get-ProvisionedAppxPackage

Choose Get-Process (right,right,right,space). Now the cmdline shows

    Get-Process _

Hit [-][ctrl-space]. Powershell now shows:

    PS C:\Users\zaphod> Get-Process -Name
    Name                 IncludeUserName      FileVersionInfo      ErrorAction          ErrorVariable        OutVariable
    Id                   ComputerName         Verbose              WarningAction        WarningVariable      OutBuffer
    InputObject          Module               Debug                InformationAction    InformationVariable  PipelineVariable

Pick "Name" and hit space:

    PS C:\Users\zaphod> Get-Process -Name _

Now hit [ctrl-space] again. PowerShell now completes on running processes on the system, offering the list of all of the process names.
