accessing imput scripts

This is what I am having trouble with. I know how to add new axis and such, but cannot find out how to open the window to write new script. How do I access the actual scripts for the imput manager? It's probably an obvious thing,like a nearby button it's just eluding me....I can't find it anywhere. how do I open the window to write the "get.axis.etc" script for my new imput....sorry for being ignorant.

Ah well. Then you probably need to go through these tutorials to get yourself up to speed on scripting! It's not exactly a button as such- you need to implement your script as a component on a gameObject- to create the script, right-click on your project view and click the Create -> Javascript or C#

I know I do need to go through these tutorials...and thank you for pointing me in the right direction. but is there no way to access the existing scripts for the game controls in imput manager...and just add more scripts for the controls I wish to add? or do I just open up imput manager and "add component- script"and write the script from scratch? does this script need to be anywhere in particular I guess is what I'm asking...every time I add a script it seems to go into new behavior script in the project bar. is this right?

" do I just open up imput manager and "add component- script"and write the script from scratch" <- This. Except you'll want to add the script component to the relevant GameObject (in the hierarchy). The Input Manager isn't something you can add scripts to. To manipulate how input affects the world you'll have to write your own scripts. You should go over the tutorials scylamoth mentioned and the rest of the Unity manual (highly recommended) and then a lot of things will be much clearer :)
