Changing animation sequence of player
I have a few different animations for the character in my game, and idle, up, and forward. Idle is the default but when he goes up in the screen by pressing the Up arrow I want the animation to change to the "up" version and when I don't press the up arrow key I want the player to go back to the idle animation. I am using the "Repeat while key is pressed" and the change animation sequence in the event editor, thinking that when the key is not pressed it would go back to the idle animation but it doesn't. Any ideas?

Think about it. Your second line of code says whenever the Up arrow isn't pressed, do that action. This will trigger even if you use the other arrow keys as long as you're not pressing Up. You need to add the other key presses that are negated in the same line of code so it tests for all the buttons not being pressed and not just the Up button.
If you didn't know, you can have multiple conditions within one line of code. Right click and add another condition to test for the other key presses.
