ASCII codes by character
The ASCII table on this site is keyed by number, which is the wrong way round for the question people usually have: you know the character and you want the code. This is the same 128 code points, keyed by name.
The names here are the ones people type. Code 92 is filed under backslash rather than its formal name of reverse solidus, and 64 under at sign rather than commercial at — the formal name is on the page, not in the URL.
