Look it up, copy it, link straight to the row
Tables worth bookmarking rather than re-searching: what a status code means, which character sits at a given code point. Each page is searchable, every row copies with one click, and rows are individually linkable, so you can send a colleague the exact line rather than the whole table.
What people use these for
- Find what an HTTP status code means and when to use it
- Convert between ASCII, decimal and hexadecimal
- Copy a value straight into your code
