In Basketball, lane shooting is taking shots from inside the free throw lane. This is usually difficult because of the number of defenders.

A lane violation is when a player tries to get a rebound before the ball gets to touch the rim during a free throw (high school rules). A key violation or "3 in the key" is when a player (offensive player or defensive player) is under the basket (known as the "paint") for more than 3 seconds.
There are many violations of basketball. You can not move with the ball when you are not dribbling. That is called a travel. The only exception is when you take two steps for a layup. You can not dribble the ball, pick it up, and then dribble again. That is called a double dribble. If you are on offense, you can not stay in the key for longer then 3 seconds or else you will get a 3 seconds call. You have 5 seconds to throw the ball in when it is out of bounds. If you don't get the ball inbounds in time it will be a turnover. You have 10 seconds to get the ball down the court onto the opposite half to which the ball was thrown in. If you don't get it across halfcourt on time that will be a turnover. These are just a few of the many violations.
This varies state by state. In some states it is a moving violation.
Foul and violation.
