@BruRomeo, there is a newer version of PSReadLine available, 2.0.0-rc1, this probably will resolve the issue (platform not supported exception).

You are running this on Windows right? less isn't used on Windows. The help command is from PowerShell, so this repository won't be able to help much with the less issue, but its interesting.

The PageDown exception has been fixed in #1032. Please try out the 2.0.0-rc1 from PowerShell Gallery.

@BruRomeo It looks to me the distro of Linux you are using doesn't have uname and less commands. The PowerShell function help uses more.com on Windows and less on Linux/macOS to display the help content.
