Since updating to Windows 10 v1809, pressing Shift+Space no longer sends a space in Powershell v5. If I use an older Windows 10 station (v1709), Shift+Space sends a space.

For example, I'm accustomed to pressing the following sequence of keys:

g, c, i, Shift+Space, |.

In v1803, this would result with gci |. In v1809, the result is gci|.

Is this key combination conflicting with something recently introduced? The problem is reproducible on multiple stations. If I'm working in a text editor, the problem doesn't exist. Launching PS with -NoProfile has no impact.

Additionally, this has only affected my installation of PS 5.1. In my installation of PS Core 6.0.2, Shift+Space still sends a space.

It seems like you need to update the PowerShellGet and PSReadLine Module to make shift+space work again.

  1. Open PowerShell as admin
  2. Run install-module -name powershellget -force
  3. Restart PowerShell (as admin)
  4. Run install-module -name psreadline -allowprerelease -force
  5. Restart PowerShell again

This should do it and it should work again.

    This worked for me as well. I didn't have to reinstall powershellget and I was able to install it only for the current user with the -User flag. (Also, I don't have a -AllowPrerelease parameter for Install-Module. Not sure if that's related to the powershellget install, but it worked fine without as of today.) – Soren Bjornstad Jul 2 '19 at 12:37
  • Yep, upgrading to 2.0.0 beta4 fixed it for me – Jaykul Jul 17 '19 at 19:03
  • The second install-module failed here with insufficient privileges. Yes, I'm a local administrator. Yes, I was running in an elevated Powershell. No matter, though, as I've got my shift-space sequence back, thank you. – roaima Jan 22 at 23:30
  • Thank you, this has been annoying me for months because I very regularly am accidentally holding shift when I press space in prep to add a pipe! For me, even running as admin, I also had to add -scope CurrentUser to get the psreadline to install, but its working perfectly after that. – Panomosh Feb 7 at 9:08

This seems to be "broken" again in PowerShell 5.1.x. That is, Get-PSReadLineKeyHandler shows no mapping associated with Shift+Spacebar, and pressing shift+space has no effect whatsoever.

Explicitly enabling it with Set-PSReadLineKeyHandler -Chord Shift+Spacebar -Function SelfInsert fixes the issue (pressing shift+space inserts space character), but the mapping will not show in the Get-PSReadLineKeyHandler listing as is, but as plain Space mapping.
