Scratch

using

change [ghost v] effect by [-1]

you can make it fade in (what you're asking for). if you change any of the effects by a negative number, they would move backward compared to putting in a positive number.

This is What I did.

when gf clicked
forever if <key [down arrow v] pressed?>
  change [ghost v] effect by (-1)

Well, you have to have this:

when gf clicked
set [ghost v] effect to (100)
forever if <key [down arrow v] pressed?>
  change [ghost v] effect by (-1)

That way, it'll go from fully transparent (100) to non transparent (0). I could give you a more complicated script that would make it fade in then out then in then out, but I don't think you want that.

But if you don't mind one last question is there any way to make the effect more stable?
I mean it works, but it wont always go back to 0% transparency when holding down the button. If you hold down the button too long it will flicker between fully there and slightly transparent.

I don't know why that would be happening, but you can do this (it'll not flicker)

when gf clicked
set [ghost v] to [100] //variable
set [ghost v] effect to [100]
forever
if <not<<(ghost)=[0]>or<(ghost) < [0] >>>
if <key [down v] pressed?>
change [ghost v] effect by [-1]
change [ghost v] by [-1]
else
set [ghost v] effect to [0] //scripts
set [ghost v] to [0] //scripts
end

and whenever you want to reset it, you just have another script that'll have this:

set [ghost v] to [100]
set [ghost v] effect to [100]

To check if it's your computer's problem, put the two blocks that have the comment "scripts" on them in the else, to check if it's your other scripts, take out the blocks that have the comment "scripts" on them.

If it's your computer's problem, I don't know what to tell you.

I usually use
repeat 100
change ghost effect by -1
