Change text case in the editor
You can use menu commands or keyboard shortcuts to convert the case of selected text to all upper case or to all lower case.
Note
The dialog boxes and menu commands you see might differ from those described in this article, which are based on the General environment settings. To change your environment settings, choose Tools > Import and Export Settings, and then choose Reset all settings.
To change text case
Select the text you want to convert.
To convert text to all upper case, choose Edit > Advanced > Make Uppercase or press Ctrl+Shift+U.
To convert text to all lower case, choose Edit > Advanced > Make Lowercase or press Ctrl+U. (If you have the C++ development workload installed, this keybinding may be used by a different command.)
Tip
To revert to the previous case formatting before this change, select Undo from the Edit menu.
