Emulate a keyboard button via the Command Line

Question

My keyboard doesn't have a Num Lock key, and none of the registry edits work for some reason.

Can I use the Command Prompt or PowerShell on Windows 10 to "press" a key? I'm looking for something like press pgup to press the Page Up Key in the Command Prompt or PowerShell, but for Num Lock.

Answer 1

How do I toggle numlock status using PowerShell.

Use the following script:

$wsh = New-Object -ComObject WScript.Shell
$wsh.SendKeys('{NUMLOCK}')

As pointed out by ABashore in his comment this can be shortened as follows:

$wshell.SendKeys('{NUMLOCK}')

Answer 2

Here's a powershell line that will toggle your NUMLOCK. I've tested this and it works on my Logitech K120 USB keyboard.

$wshell.SendKeys('{NUMLOCK}')

Here's a list of the other SendKey codes.

If you need to send the keystroke to an interactive application, more code will be needed.

Batch

Without creating temporary files. The 'loop' was shown only so that you could open a notebook for output. Remove it after.

    @echo off
        :loop
            ::------------begin main code------------
            set command=new ActiveXObject('WScript.Shell').SendKeys('WoW{ENTER}{ENTER}');
            for /f "delims=" %%i in ('mshta "javascript:%command%close(new ActiveXObject('Scripting.FileSystemObject'));"') do set
            ::-------------end main code-------------
            timeout /t 1 /nobreak >nul
        goto :loop
