It can also indicate a line break when quoting poetry, such as "Mary had a little lamb / its fleece was white as snow." Sometimes, the oblique replaces a hyphen or dash to denote a strong joint between words as in "the Hemingway/Faulkner generation.
Abbreviations make use of the oblique symbol as well, for example "w/e" is short for "whatever" and "i/o" stands for "input/output."
