Edit button in teasers i'm using display suite and views in one of my teaser content type and i'm trying to add an EDIT button right in the teaser, but i can't find the function to do this. So i came here to ask for help. Can you help me? Thank you
The edit function is usually provided in teasers with contextual links. 

Activate the optional core module, and when the teaser is displayed, a contextual links icon will be displayed at the upper right corner of the rendered teaser.
