Short description of error
Uv/Image Editor. I cannot add a shortcut with the rmb menu to the menu item Mirror / X Axis.
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
Open Blender, unwrap a primitive. Go to UV/Image Editor / UVs / Mirror / X Axis. Right click at it. Try to assign a hotkey. The Assign Hotkey menu entry is missing.
