It's in scan type list. I had read the wiki, but not found it.

When doing a changed/unchanged/increased/decreased scan session this comes in handy in cases where you get distracted and don't know anymore if the value got changed or not

with this scan you update all values to the current value without removing any address from the list. And from that point on you can continue

I don't get it.
Can you give me an example？

[Dark Byte]

you're looking for health but you don't know the value

you do an unknown initial value
you get hit, so you do an decreased value scan
nothing happens for a while: unchanged value
get hit again, decreased value
then you drop your mouse on the ground and while picking it up you hear an explosion, but you don't know if was close enough to hurt you
then you do an ignore value scan and continue with the normal routine of decreased/increased/unchanged

THX.
It means maybe I missed changed vaule or not, then do "ignore value", it can refresh the value to current vaule.
