In if-statements:

-1 is the previous character, 0 is the current, and 1 is the next.
* Equals sign (=) checks to see if the character under consideration
is equal to a character.
* Period (.) plus a word sends the module to the corresponding entry
in the letter's data table.
* Tilde (~) calls a function on the character under consideration,
if the function exists.
