1. A computer-implemented method comprising: identifying a word that includes modifiable characters; correlating a different numerical value of a first set of numerical values with each individual character of the modifiable characters; and causing a second set of numerical values to be displayed in response to a selection of one of the numerical values of the first set of numerical values, each numerical value of the second set of numerical values being associated with a different character modification and being selectable to cause one of the modifiable characters correlated with the one of the numerical values of the first set of numerical values to be modified such that each of the modifiable characters is individually modifiable.
