What is the key to use your "flipper senses"?

[ZedClampet]

To locate dirt, etc. I could swear it said something about that, but there is nothing under the key rebinds for it, and I can't find it. Maybe I just dreamt it.

Q by default

It should also have an eye icon and say the key at the lower left of the screen when its available

I found that it turns on if I hold a brush/rag/spray in my hands

supposedly, it will show whatever is related to the tool you're holding. so the vacuum will show debris on the floor.

it doesn't highlight it for very long though. and once you start using the tool again, it usually fades out.

at least with the spray (once you get that) you can make your own dirt highlighter, of sorts.

i just cleaned probably the dirtiest house in the game--dirt on every surface, facing all directions (there was even dirt up on the flat roof). finally got a perk in that.

Q but it is annoying to have to use that, I prefer the HL1 method where it just shows everything on the mini map once ya get the perks

The most annoying thing about "flipper sense" is that you only see the highlight when you are looking at it (assuming it isn't obstructed by a piece of furniture). The "flipper sense" gives you no indication about where to look - the floor, the ceiling, what direction, etc. In that respect, the minimap in the first game was a lot more useful.

Also there seems to be no lore reason why some stains are literally invisible without using "flipper sense"
