Can I make a multi-line selection of text all capitals in Visual Studio Code?
In full Visual Studio it\'s CTRL+SHIFT+U>
In Linux and Mac there are not default shortcuts, so try to set your custom shortcut and be careful about don't choose a hotkey used (For example, CTRL+U is taken for uncomment)
In my case I have CTRL+U CTRL+U for transform to uppercase and CTRL+L CTRL+L for transform to lowercase
Just in case, for Mac instead of CTRL I used ⌘
