How to create the single quote symbol
Creating the single quote symbol on a U.S. keyboard

What is a single quote used for on a computer?
In most computer programming, single quotes are commonly used to contain commands or literal strings.
my $example = "Example of variable";
print 'Do not print $example';
In the example above, the variable $example would not be treated as a variable. Instead, it would print "Do not print $example". If you used quotes instead of a single quote, it would print "Do not print Example of variable".
In other programming languages, like QBasic and Visual Basic, the single quote is treated as a nonexecutable statement.
In Microsoft Excel, an apostrophe causes Excel to treat the text entered into a cell after the apostrophe as text instead of a number.
A single quote may be used when describing a measurement. For example, if someone said they're 5' 9", it's the same as saying they're five feet nine inches.
When describing measurements, it's more proper to use a single prime instead of a single quote.
A single quote may be used in a keyboard shortcut. For example, pressing Ctrl+' in Microsoft Excel copies the formula in the cell above the selected cell.
What is the other symbol on the single quote key?
On U.S. keyboards, the single quote key is shared with the quote key, which may be shown next to or above the single quote symbol.
