If you want to manually modify the shader's code, you can do that in the Quick Shader area.
Enable – Makes the Quick Shader's text area active.
Once enabled, place the original code inside the text area. Alternatively, start writing in the blank area your own code.
If you have already loaded a shader in the material parameters, right-click on it and select Open in QuickShader option.
Another way to do this is to activate the text area and drag and drop the .osl file in there. It will load the code instantly.
Right-clicking on the Quick Shader panel opens a context menu. You can Compile the code after doing changes or Compile and Reset Parameters, which affects the values of the parameters in the shader as well.

The shader file originally loaded in the material (if any) will not be affected in the compilation. You need to manually save your code.
