Quick Reveal of Formulae
To quickly show all formulas in your Excel spreadsheet
Hold down the CONTROL key on the keyboard and press the grave accent key ( ` ). This is located to the left of No 1 key on the top left corner of the keyboard and looks like a backwards apostrophe.
Revealing the formulas does not change the spreadsheet, but enables you to check the formulas.

Repeating this step will return you back to the normal view of your spreadsheet

I am happy of this keyboard shortcat. I need to no all the keys shortcat if it is posible you send to my mail.
thanks
