How to assign a double click as a keyboard shortcut I've tried searching for this seemingly obvious topic. The following article has been the most accurate and detailed I've found so far for what I'm trying to do (see Benu's reply): 

http://blenderartists.org/forum/archive/index.php/t-376596.html

It's from Jul 2015, so not too old. Except it describes a left dropdown list and right dropdown list in the User Preferences, next to individual shortcuts, which I do not have. Nor a "double click" option. I'm just finding my way around Blender, version 2.76b. Best I can do is selecting "Mouse" in the device dropdown list and enter "Right click" (or left) as event. No other fields.

What am I missing? 

Thanks!
Under Blender User Preferences > Input > 3D View > Mesh

Add a new keyboard entry with the operator mesh.loop_select change input type to Mouse and select Left > Double Click
