Dactylology (fingerspelling) is not used just one way. Someone using the Rochester Method will use the ABC's much differently than a person using ASL. Same alphabet but put to use differently. ASL uses the alphabet to spell proper names and titles, technical terms, and jargon. ASL also uses the alphabet in "loan signs" and specially constructed abbreviations and acronyms that incorporate specific movements in the spelling. PSE/SEE signers use the alphabet to initialize basic ASL sign forms or modify signs for English use (such as using the V hand shapes for HAVE).
