IgnoreCase

IgnoreCase is an option for string manipulation and searching functions which specifies whether lower- and upper-case letters should be treated as equivalent.

With the default setting IgnoreCase -> False, lower- and upper-case letters are treated as totally different.

With the setting IgnoreCase -> True, lower- and upper-case letters are treated as equivalent.

IgnoreCase is an option for StringPosition, StringReplace, StringMatchQ, Find and FindList.

IgnoreCase in no way affects the parsing of Mathematica expressions.
