Foswiki defines some standard special tokens that can be used to replace characters in some parameters - notably those to 
FormattedSearch and 
IfStatements - to defer evaluation of the parameter until later. These special tokens are often called "escapes", because they allow the character to "escape" from its normal meaning. 
	
		
			 $n or $n()  | 
			 New line. Use $n() if followed by alphanumeric character, e.g. write Foo$n()Bar instead of Foo$nBar   Most macros accept parameter strings which are split over multiple lines. This is usually more readable than using $n tokens. If you are familiar with sectional includes, you might also consider nested sectional includes to hold the newline content outside of the parameter string entirely.     Note that newline is not a line break.  The browser will wrap the lines together. If you require a line break, displaying the results on two lines, use %BR%.  Or use two consecutive newlines to create a TML "Paragraph".   | 
		
		
			 $nop or $nop()  | 
			 Is a "no operation". This token gets removed; useful for nested search  | 
		
		
			 $quot  | 
			 Double quote (") (\" also works)  | 
		
		
			 $percent  | 
			 Percent sign (%) ($percnt also works)  | 
		
		
			 $dollar  | 
			 Dollar sign ($)  | 
		
		
			 $lt  | 
			 Less than sign (<)  | 
		
		
			 $gt  | 
			 Greater than sign (>)  | 
		
		
			 $amp  | 
			 Ampersand (&)  | 
		
		
			 $comma  | 
			 Comma (,)  | 
		
	
If you ever find yourself needing to escape an escape, you can use 
$dollar to escape the leading dollar, thus: 
$dollarpercent.
