**Short description of error**
For GLSL (Blender game) or BI material nodes, there is no UI of the node wrangler. Not even the spacebar search works.
Tried removing all traces of Blender from my system, re-installing, even downloading a non-installer version, nothing worked.
Strangely, it works in some other node editor modes, like compo
**Exact steps for others to reproduce the error**
- Switch Render Engine to Blender Internal or to Blender Game
- create a node material
- try e.g. ctrl-space or space - search for an operator in node editor
note: Didn't test texture nodes.
