Set-PSReadLineKeyHandler get registered but cant be triggered-CodePudding

Set-PSReadLineKeyHandler not working. If I for example define:

Set-PSReadLineKeyHandler -Chord shift B -ScriptBlock {
"Line 1"
"Line 2"
"Line 3"
}

And then run Get-PSReadLineKeyHandler just to see the user define actions:

Key Function Description  
--- -------- -----------  
Ctrl j CustomAction User defined action  
Ctrl B CustomAction User defined action  
B CustomAction User defined action

When it comes time to trigger the hotkeys nothing happens. None of the user defined hotkeys for actions trigger. No errors, just nothing.

PSVersion 7.3.0-preview.7

PSReadLine 2.2.6

Windows Terminal Preview 1.15.2003.0

Thanks for helping me.

As Otter's comment says, to write text or move the cursor around you need to call methods to make PSReadLine do those things. See the Set-PSReadLineKeyHandler documentation, e.g. example 2:

This example shows how a single key can be used to run a command. The command binds the key Ctrl B to a script block that clears the line, inserts the word "build", and then accepts the line.

Set-PSReadLineKeyHandler -Chord Ctrl B -ScriptBlock {
    [Microsoft.PowerShell.PSConsoleReadLine]::RevertLine()
    [Microsoft.PowerShell.PSConsoleReadLine]::Insert('build')
    [Microsoft.PowerShell.PSConsoleReadLine]::AcceptLine()
}

At a PowerShell prompt you can start typing [Microsoft.PowerShell.PSConsoleReadLine]:: and then press Ctrl Space to get an autocomplete view of available methods; they are documented here.
