◊ ( define - meta title "signature lines" )
◊ hanging - topic [ ( topic - from - metas metas ) ] { Type a sequence of underscores }
A ◊ em { signature line } is a horizontal line aligned with adjacent text .
Typography purists avoid accomplishing anything by holding down keys on the keyboard . But in this case it ’ s the simplest solution . To make a signature line , hold down the underscore key ( shift + hyphen ) until you get the length you need .

A rival school of thought suggests you should type a series of word spaces and format them with underlining .

Same thing , right ? Not quite . There are three good reasons to prefer underscores to underlined word spaces .
◊ numbered - list {
If you need to quickly rid a document of underlining , you might want to select all the text and then uncheck the underlining option . But this will wreck signature lines made out of underlined word spaces — they will disappear .
If you need to quickly ensure you only have one space between sentences , you might want to search for and replace any double spaces . But this will also wreck signature lines made out of word spaces — by partially deleting them .
Underscore characters don ’ t depend on formatting , so they will look the same no matter where they ’ re copied and pasted . Underlined word spaces may not .
