powershell psreadline key handler

gistfile1.txt

Description
The Set-PSReadLineKeyHandler cmdlet customizes the result when a key or sequence of keys is pressed. With user-defined key bindings, you can do almost anything that's possible from within a PowerShell script.

Examples
Example 1: Bind the arrow key to a function
This command binds the up arrow key to the HistorySearchBackward function. This function searches command history for command lines that start with the current contents of the command line.

PowerShell

Copy
Set-PSReadLineKeyHandler -Chord UpArrow -Function HistorySearchBackward


Example 2: Bind a key to a script block
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.

PowerShell

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