The manual is a skateboarding trick similar to a bycycle wheelie where the rider balances with the front/back wheels off and without the tail/nose on the ground. Manuals can be done with both feet or one. In one-footed manuals the rider place one foot parallel to the board and balances on the nose/tail. A maual in which both feet are straight on the nose is a Hang-ten manual, its tail counterpart is called a Heelie. The most difficult variation is the Swedish manual/nose manual, mostlikely named after Swedish pro Stefan "Lillis" Akesson, where the rider places on foot underneath the truck and the back foot futher up the deck.
