Extention not found

[AndrewKralovec]

I installed the change-case extension Added a short cut

// Place your key bindings in this file to overwrite the defaults
[
  { "key": "ctrl+shift+l",   "command": "editor.action.copyLinesDownAction",
                                     "when": "editorTextFocus" }, 
{ "key": "ctrl+shift+o", "command": "extension.changeCase.upper", "when": "editorTextFocus" }
]

But it shows `

command 'extension.changeCase.upper' not found

`

Hello @AndrewKralovec, I tried exactly the same, and it's working for me. Is it working without the keyboard shortcut? Try Ctrl/Cmd+Shift+P, then type 'upper'. Do you see 'Change case upper' in the completion list? If not, maybe you could try uninstalling and then installing the extension again.
