Unless you have the Home Edition, I suggest you use the Insert Character feature. Also be sure to add a dollar sign before the value, in case you want to add a hexadecimal value. For example to enter decimal value 61158, you either add that as decimal value (thus without $ sign) or its hexadecimal equivalent $EEE6.
