I know I'm going to look like a noob for asking this but somehow I forgot. What does that white line in the curves menu for? It's embarrassing because most of you that know me know I'm not new to Gimp, It's a stroke thing, I can't remember some things when I want to.

when you use the curves tool, the mousepointer becomes a colourpicker
when you click into an image, the line appears where the colour is on the histogram

Dur! don't worry GMS I didn't know that

Yeah, I knew that, just testing you. (mumbling)

Ok, what does the number mean?

tonal scale, a value between 0 and 255

Yup, that's right, I wanted to make sure you understood it. I'm not full of mind altering drugs and I remembered that part this morning.
