You activate all the Excel 2016 hot keys by pressing down the Alt key before you type the various sequences of mnemonic letters. All the hot key sequences for selecting the most common formula-related commands in Excel 2016x begin with the sequence Alt+M because the M in forMulas was the only mnemonic key still available. (F was already assigned to the File menu commands.)

After you know to press Alt+M to access one of the commands on the Formula tab of the Ribbon, it's pretty easy sailing, if for no other reason than the commands on the Formula tab are pretty evenly and logically laid out.
