Which keyboard shortcut is used to change the case of selected text in Microsoft Word?

In Microsoft Word, the keyboard shortcut Shift + F3 is used to cycle through different text cases for selected text: Sentence case, lowercase, and UPPERCASE. This is a highly efficient way to adjust text formatting without using the mouse.

• "Ctrl + Shift + A" (A) is used to toggle all caps for selected text.
• "Ctrl + F3" (C) is used to cut selected text to the Spike (a special clipboard).
• "Alt + F3" (D) is used to create a new building block from selected text. Therefore, Shift + F3 is the specific shortcut for changing case cyclically.
