I feel silly for asking this but it isn't like I could google this.
What is the ` character called? In case it doesnt show up, it is the character used for inline code with markdown. Also, on most keyboards, it shares the key with ~.
I like all three answers so I made this a CW instead of accepting
Grave (pronounced Grahv, not like the synonym for tomb) or Grave accent.
All sorts of things, but in programming mostly the back-quote or backtick,
You can use Unicode table to find name of the symbol. There are utilities which let you search it, like gucharmap. It gives U+0060 GRAVE ACCENT for this symbol.
From the Jargon file, the prime nerd reference which really should be an ISO standard :-)
Common: backquote; left quote; left single quote; open quote; ; grave.
Rare: backprime; backspark; unapostrophe; birk; blugle; back tick; back glitch; push; opening single quotation mark; quasiquote.
This answer or this answer provides a good definition.
In laymen's terms "no-shift-tilde" is also useful in PHP for keeping mySQL statements from crashing on single quotes on the table name.
SELECT * from `the_table_name` WHERE id=1 // best practice
For some reason certain PHP servers will choke on this:
SELECT * from 'the_table_name' WHERE id=1 // not preferred method
This normally works, but doesn't pass nice in strings:
SELECT * from "the_table_name" WHERE id=1 // how to escape this string?
Other than that, I don't use it much.
