How to test for a keypress or continue in powershell - powershell

Question

I have a basic powershell function that works as a spambot.
function Start-Spambot{
[CmdletBinding()]
param(
[Parameter(Mandatory=$True,HelpMessage="The text you wish to spam.")]
[string]$text,
[Parameter(Mandatory=$True,HelpMessage="How many milliseconds between messages.")]
[decimal]$speed,
[Parameter(Mandatory=$True,HelpMessage="The tota ammout you want to spam.")]
[decimal]$number
)
$count = $number
Invoke-BalloonTip -Message "You have 3 seconds before the program starts spamming." -Title "Start-Spambot $text $speed $number"
Start-Sleep -Seconds 3
while ($count -gt 0){
[System.Windows.Forms.SendKeys]::SendWait("$text")
[System.Windows.Forms.SendKeys]::SendWait("{ENTER}")
Start-Sleep -Milliseconds $speed
$count -= 1
}
[System.Windows.Forms.SendKeys]::SendWait("$text")
Invoke-BalloonTip -Message "$text has been typed $number times." -Title "Start-Spambot $text $speed $number"
}
The thing i want to add is a kill switch in the while loop. If you press 'esc' for example the script should break the while loop and continue as normal. (invoke-balloontip will make a popup in the bottem right). I have looked at a bunch and googled for hours but they all are just looking to go if the key is pressed and not the other way arround.
Any of you have a simple script or function for this?
Note:
(All of you who are complaining i dont have the code that i tried. Why would i save the things that dont work?)
Edit:
If possible it should work outside of the terminal.

Answer 1

After more searching i finaly found this method:
Add-Type -AssemblyName WindowsBase
Add-Type -AssemblyName PresentationCore
1..10000000 | ForEach-Object {
"I am at $_"
$isDown = [Windows.Input.Keyboard]::IsKeyDown([System.Windows.Input.Key]::LeftShift)
if ($isDown){
Write-Warning "ABORTED!!"
break
}
start-sleep -Milliseconds 10
}
Edit:
It wont work in the ise wich is kinda anoying
