Why is Loop Cut and Slide not in the CTRL+E/F menu? How can I get to Loop Cut and Slide via a popup menu? I can only find it in the T side bar.

Neither W nor any of the Ctrl+E/F/V menus seem to show me the Loop Cut and Slide tool.

I seem to only be able to find it in the T bar on the left. Am I missing another popup menu shortcut available for modelling operations? I'm a newcomer to Blender.
You are correct, Loop Cut and Slide is available currently only as a shortcut (Ctrl-R) and in the Toolshelf, in the Mesh Tools panel, as stated here: https://www.blender.org/manual/modeling/meshes/editing/subdividing/loop_subdivide.html
