Alt+Shift+DownKey to box-select beginning of each string followed by Ctrl+V pastes only on the first line.
Expected behavior: paste my string on all selected lines.
Using Notepad++ v5.9
1) Mark
2) Push Alt+c to open Column editor
3) Enter text there
As commented by @chapo it now works fine with Alt-Shift-Down and then pasting.
 
    
    Can you select your column with Alt+Shift+Down, type in a single unique character then use Search+Replace to get your text inserted the way you want?
