TrailRenderer Easy C / C# Script - Unity

Hello,

I want to have trails for my character. So I added the script TrailRenderer to my character.

The trail is working, so this is good.

However, I want 2 functions:

1. When I press a keybind, I want it to either activate/deactivate the trail for my character. I usually do this by adding a script called 'Activate (Script)', put a keybind and the GameObject but this can't work with TrailRenderer because this is not a game object.

I know you basically have to do something really easy like:

"if (Input.GetKeyDown(KeyCode.*))

{

Trail.SetActive(true);"

But I have no knowledge in coding so I prefer you to do it fast without any errors.

2. I want that when I press another keybinds, it switchs the colors of the trail of my character.

So can you do a fast script about these 2 functions ?
As this is something relatively easy, I'm looking for a cheap price, hope you understand.

Please only contact me after you did research on the problem or write the script.

Thanks
