Adjusting a GUI slider with the arrow keys? c#

Hi all,
I am trying not to use the mouse in my game. My question:
Is there any way I can adjust the value of a GUI slider using the left/right arrow keys?

My code:

void OnGUI () 
	{
		if(PauseGame.pause==true)
		{	
			
			
			hSliderValue = GUI.HorizontalSlider(new Rect(25F, 25F, 600F, 30F), hSliderValue, 0.0F, 10.0F);


				if(GUI.Button(new Rect(25,60,600,20), "Press When Finished")) 
				{
					
					
					PauseGame.pause = false;
					Time.timeScale = 1;
				return;
				}
		}
		else if(Time.timeScale ==1){
		update();
		}
	
	}

Alright, figured it out

void OnGUI () 
{
	if(PauseGame.pause==true)
	{	
		if(Input.GetKey("left"))
		{
			hSliderValue = hSliderValue -0.1F;
		}
		else if(Input.GetKey("right"))
		{
			hSliderValue = hSliderValue+0.1F;	
		}
		
		hSliderValue = GUI.HorizontalSlider(new Rect(25F, 25F, 600F, 30F), hSliderValue, 0.0F, 10.0F);

			if(GUI.Button(new Rect(25,60,600,20), "Press When Finished")) 
			{
				
				
				PauseGame.pause = false;
				Time.timeScale = 1;
			return;
			}
	}
	else if(Time.timeScale ==1){
	update();
	}

}
