Currently when the @ target is used, the target is highlighted with "[" and "]" :

Add different strategies :

• SHOW : current behavior
• LEFT : the pivot become the tokens before the target
• LEFT + TARGET : the pivot become the tokens before the target + the target
• SELECT : the pivot become the target
• RIGHT + TARGET : the pivot become the target + the tokens after the target
• RIGHT : the pivot become the tokens after the target + the target
