How to open read notifications? I got a notification which was shown in my notification bar on my Google Nexus 5. As soon as I clicked on the notification an app opened and the notification has been removed from my toolbar. With the trick described here I am able to see that passed notification but I cannot open it (see screenshot). 

Is there a way to open that notification again so that the app leads me again to the content belonging to it?

Assuming I'm understanding your question correctly, you want a "pinned" notification, meaning a notification that stays in the notification bar after you tap it and open the app in question.

If I am correct, you might want to look into apps that let you create your own notifications, like the app Custom Notification.

This could clutter your app drawer a little bit though; I know referencing Tasker without a specific task is poor form, but you might check into the Tasker subreddit, and tell them exactly what you are looking for. Someone might be able to recommend a profile that pins a notification to the status bar until you are done with it.
