16. One or more computer-readable media storing computer-executable instructions that, when executed by a computing device, cause the computing device to: correlate a first set of values with characters of a word, each value of the first set of values being a different value and being associated with a single character of the characters; display modification options for a particular character of the word in response to a selection of a value of the first set of values that corresponds to the particular character, each of the modification options being associated with a value of a second set of values and including a character modification that can modify the particular character in response to a selection of a respective value of the second set of values; receive an indication of a selection of a particular value of the second set of values; and modify the particular character based on one of the modification options that corresponds to the particular value.
