Group and Ungroup on Blender ~ Have you ever using link system on Blender? To get it simple you should make a group for many object in a blend file, such as Mesh, Armature, Material, etc. If you make it in a group you just need to call the group name to link the  all object in a group. It's simple than you link every object from a group. I will try to post how to create a group of object and ungroup a object.

Create Object Group
There are many way to create a object group, but the way that i likes is using shortcut Ctrl + G. Before use the shortcut, you need to select all object that you want to add it in a group. If the object is joined in a group, the outline color of object will change to green. Dont forget to adding name in a group, it will help you when organize the object.

Ungroup the Object
Ungroup use to eliminate object from the group, so we can cancel object in a group. To ungroup object from group, i didn't find the shortcut yet. So i am using object data to ungroup the object. Just remove the group name from object data, your object will remove from the group. If you still confuse how to ungroup the object, check the picture below.

If you know the shortcut to remove an object from the group, please notify me. Because i have search on blender search and google i didn't find the shortcut yet. I hope this Blender Tips and Trick helpful.
