Expand/collapse element tree in "Edit Groups" in one click

All tree views in TestComplete (Project Explorer, Object Browser, Name Mapping, etc.) support keyboard shortcuts:

NumPad * - expands the current node and all child nodes.
NumPad – - collapses the current node.

To expand all, you can select the root node and press NumPad *. Will this work for you?

 Oh, thank you HKosova! I really forgot about numpad keyboard shortcuts. This ideally works.
