How to change capital word to small word short key?

Dear Friends:

there is no way to change case in Excel using Shortcut key. (forget)

you can use formula only (at least till now)

To apply the small capital (Small Caps) letter formatting to your text, select the text, and then on the Home tab, in the Font group, click the arrow in the lower right corner.

Click on the buttons shift 

you may use capslock or you may also use shift then press the letter you want to change

SHIFT +F3 OR YOU USE A CAPSLOCK BUTTON OR SHIFT+F3 THATS IT

To chane capital word into small word the short key use shif +F3

it is Shift+F2

try it if it doesn't worked so try Shift + F3
