Say you went to PowerShell and added a path:
$env:path += 'C:\banal\cranial\inversion'
Oops, you forgot a ; in it, it should have been
$env:path += ';C:\banal\cranial\inversion'
-- but your path is already screwed up. In zsh, we can just
vared PATH; what about PowerShell, is there a way to edit the variable instead of resetting it anew? And if resetting, how can you copy and paste just a part of it, if it wraps around?
