I have read these two to discussions

https://github.com/microsoft/terminal/pull/6062

https://github.com/microsoft/terminal/issues/15059

but as I am not a programmer, just a small time script tweaker, can anyone summarize / explain to me these two discussion in more layman terms?

I have this OK working test code

Write-Host "Last line of text"

Write-Host "Executing in:"
Write-Host



# Countdown:

$topRow = [System.Console]::CursorTop

10..0 | ForEach-Object {
    [System.Console]::SetCursorPosition(0, $topRow)

    if ($_ -eq 10) {
        Write-Host $_ -NoNewline
    } else {
        Write-Host " $_" -NoNewline
    }

    Start-Sleep -Seconds 1
    Write-Host " `b" -NoNewline
}



# Here will be the main script

Write-Host
Write-Host "Script has been executed"



# Wait for specific user input (ESC, ENTER, or SPACE) before closing the window:

Write-Host "To close this window press either:
Enter
Space
Esc"
Write-Host

do {
    $key = $Host.UI.RawUI.ReadKey('NoEcho, IncludeKeyDown').Character
} while ($key -notin @(' ', [char]13, [char]27))

which stops the PowerShell window at countdown - and after it ends it then proceeds with execution of the rest of the script

But the problem with it that I have is that every appearing digit makes the PS window scroll down its content to the very bottom - thus I can only see what is above this active counter for less than second afterl scrolling up. I can constantly scroll manually but it always goes back to the bottom to show a new digit. I could of course replace that with a silent countdown like this


$CountdownSeconds = 10
Write-Host "Executing in:"
Write-Host $CountdownSeconds
Write-Host "seconds"
Start-Sleep -Seconds $CountdownSeconds

but at a cost of not being informed then about how much time has left

So is there a way to eat a cake and have it - i.e. to see a digits of countdown at the bottom of window but also at any time to be able to scroll up not have the view thrown back down every second?
