Highlight Region of Sine Graph

I have a sine graph and I want to highlight all along the x-axis and just the [-1,1] region on the y-axis. Is this possible?

This is my code and I would like the bounds between [-1,1] on the y-axis to be shaded some color all along the x-axis. The whole area, not just the peaks and valleys.

% Do you want this?
x=linspace(0,2*pi,101);
y=sin(x);
area(x,y)

This is my code and on the graph, I would like the bounds between [-1,1] for the y-axis shaded some color all along the x-axis. Sorry if I wasn't clear. I would like the shaded region to be all across and nt just where the peaks and valleys are. Thank you.

x=linspace(-5*pi,5*pi,100); 
KP1=(6*(sin(x)/(x)))+cos(x);
for c=1:100 
    KP1(c)=(6*(sin(x(c))/(x(c))))+cos(x(c)); 
end
plot(x,KP1)

This is the whole plot:

x=linspace(-5*pi,5*pi,101); 
KP1=(6*(sin(x)./(x)))+cos(x);
plot(x,KP1)

Now what do you want to do?

Thanks for your help and patience. I would two straight lines that pass all along the x-axis at -1 and 1 on the y-axis. If the space between these two lines could be filled as well.

This is the next step:

x=linspace(-5*pi,5*pi,101); 
KP1=(6*(sin(x)./(x)))+cos(x);
hold on;
plot(x,KP1)
plot([-5*pi,5*pi],[-1,-1],'r');
plot([-5*pi,5*pi],[1,1],'r');

Amazing! Thank you!
