I recent received a windows update which updated my PowerShell build to 5.1.17763.771, this build changed the way PowerShell lets you select text in a formatted table or list results. You used to be able to selected select a point and drag down and the highlighted to text would run vertical now its running horizontal like MS word or note pad. The previous method is clearly the preferred method. Very similar in how Ctrl+Alt works in MSword. I have looked through the Get-PSReadLineKeyHandler and no luck.
You can access this setting in the properties of your console window on the tab Options. It is named "Enable line wrapping selection". ... and in my humble opinion the new way is the prefered way. It is much easier now to copy a complete command lines instead of a rectangle block. 😉
