I have a Delta compound mitre saw, there are holes in the fence which I assume must be there for something - an accessory of some sort but I don't find any reference to this. The owner's manual doesn't mention anything. Below is a link to a closeup view of a similar model where the holes are clearly visible.

Anyone know?

Thanks.

Use them to screw on a taller fence if you need one. That's what they
are for.

That's *one* of the things they are for. ;-)

They are there so that you can attach an auxiliary fence, such as a zero-clearance fence.

A zero clearance fence is a fence with no gap around the blade. It prevents tear out at
the back of the board being cut. If you attached a single long piece of woof with screws
through those holes and then cut through it with the blade, the opening will be the exact
same width as the saw kerf. This will provide support to the board that you want to cut
cleanly. Mark each side so you can remove and reinstall as needed.

You can also make a zero clearance insert for the base of the saw to prevent tearout under
the board being cut.

Google 'zero clearance fence (or insert) for miter saw' for more info and videos.

To hang it up if you do not need a fence.

The holes are so you can fasten on a fooden face to the fence.
Usually as a "fence stretcher"

Usually? If you mean "stretcher" in the vertical direction, then maybe.

In my experience, the holes are "usually" used for a taller fence or a
zero clearance fence, not a longer fence.

When a longer fence is required, it is "usually" used as part a miter saw
station with the original fence of the miter saw (or an auxiliary fence
of the same length as the original) flush with the miter station's longer
fence.

I did an image search for 'miter saw fence extension' and 'miter saw fence
stretcher' and had a really hard time finding images of long fences attached
directly to the original. Kreg carries a "Trak & Stop System" which includes
plans for a long fence that is attached to the original fence, but that's a
rare case and done mainly to ensure the accuracy of the Stop's measuring
tape.

I'm not sure "usually" applies to the use of the holes when discussing a
fence extension.

Sometimes you need a "board stretcher" so the fence is longer :-\
