Using Regex for special search and replace
- 
 Sorry for my english. It’s not my mother tongue. Let’s say I have a text like the following Lorem ipsum dolor sit amet, consectetur adipiscing elit. ~Praesent~ condimentum, ligula et egestas pretium, magna nunc tincidunt mauris, at fermentum ~massa~ enim ut mi. Ut ac faucibus lacus. Donec vel est ~et~ justo posuere vulputate. Donec viverra id neque eget vehicula. Donec luctus pharetra odio vitae fringilla. Integer dictum hendrerit congue. ~Pellentesque~ maximus fermentum nulla sed pulvinar. Nulla nisi lorem, interdum ~non~ sagittis nec, posuere a massa. ~Sed~ vitae ex ac ~eros~ dapibus iaculis. Sed ~sit~ amet augue eu justo ultricies facilisis. Pellentesque rhoncus ipsum ligula, at rhoncus mi sollicitudin in. NOTE: Some words are delimited with ~ like ~non~ I know I can find words using regex for example using: ~[A-Z][A-Z][A-Z]~ But I have trouble when trying to replace them. For example i would find ~Sed~ and ~non~ Then when replacing lines all become $[A-Z][A-Z][A-Z]& 
 and I would like to have $Sed& and $non&Because when I do all become the same word. Question 1: 
 Would it be possible to find them regardless the character number. Find ~Praesent~ and ~sed~At the moment i use ~[A-Z][A-Z][A-Z]~ then i find words with 3 characters Question 2: 
 How can I replace only the beging and ending of this words. By this I mean changing
 ~sed~ for \textbf{sed}
 ~Praesent~ for \textbf{Praesent}Is this possible? Thank you very much. Jorge

Ut ac faucibus lacus. Donec vel est ~et~ justo posuere vulputate. Donec viverra id neque eget vehicula. Donec luctus pharetra odio vitae fringilla. Integer dictum hendrerit congue. ~Pellentesque~ maximus fermentum nulla sed pulvinar. Nulla nisi lorem, interdum ~non~ sagittis nec, posuere a massa. ~Sed~ vitae ex ac ~eros~ dapibus iaculis. Sed ~sit~ amet augue eu justo ultricies facilisis. Pellentesque rhoncus ipsum ligula, at rhoncus mi sollicitudin in. to this: Lorem ipsum dolor sit amet, consectetur adipiscing elit. \textbf{Praesent} condimentum, ligula et egestas pretium, magna nunc tincidunt mauris, at fermentum \textbf{massa} enim ut mi.
