Make selected block of text uppercase

Whenever you want to do something in VS Code and don't know how, it's a good idea to bring up the command palette with CTRL+SHIFT+P (CMD+SHIFT+P on mac), and try typing in a keyword for you want. Oftentimes the command will show up there so you don't have to go searching the net for how to do something.

Highlight the text you want to uppercase. Then hit CTRL+SHIFT+P to bring up the command palette. Then start typing the word "uppercase", and you'll see the Transform to Uppercase command. Click that and it will make your text uppercase.

The question is about how to make CTRL+SHIFT+U work in Visual Studio Code. Here is how to do it in version 1.57.1 or above.

Steps:

1. Open Visual Studio Code.

2. Press CTRL+SHIFT+P.

3. Type

   open keyboard shortcuts
   

4. Select

   Open keyboard shortcuts (json)

An editor will appear with keybindings.json file. Place the following JSON in there and save:

[
    {
        "key": "ctrl+shift+u",
        "command": "editor.action.transformToUppercase",
        "when": "editorTextFocus"
    },
    {
        "key": "ctrl+shift+l",
        "command": "editor.action.transformToLowercase",
        "when": "editorTextFocus"
    }
]

Now CTRL+SHIFT+U will capitalise selected text, even if multi line. In the same way, CTRL+SHIFT+L will make selected text lowercase.

These commands are built into VS Code and no extensions are required to make them work.

Do the same for lower case.

Note

In the new versions (eg 1.57.x) of VS Code, Ctrl+Shift+L is a shortcut for bulk selecting all selected text occurrences. So you can use another combination, like Ctrl+Shift+/ etc.
