My mnemonic for distinguishing between the two is think of the slash glyph as a stick figure. The one about to fall on his face is forward and the one ready to fall his behind is the backslash. Or we can put on airs and astound folks with our erudition, referring to them as virgules, eh? :-)
Other esoteric and more conventional terms for characters are:
# - octothorpe (hash) ^ - circumflex (caret) ` - grave accent (backtick)The ASCII character set packed a lot of information into the sparse 7 bits it had available.
