node group problem.

Hello, all.
I have a question.
If i make a group-node then i open the node-group again so i can see the whole node group, but then i want it go into that small node-group node thing again.
How can i do that?
click somewhere other then the whole node-group won’t work.
0Can someone help me?
Ty, already.

The Tab key toggles between the minimised and expanded group view

Ty, so much.
