I rebind my sneak key to the number pad period key since I use arrow keys for navigation. Documentation often makes errors in referring to the sneak key as "Shift". This is the case with Dimensional Pockets. I can not do a sneak-right click to enter/exit the dimension or use it to pick up the Pocket Dimension with my rebound sneak key. I can do these things only if I rebind the sneak key to its default Shift.
