I'm after something like an Acrow prop but with a length in the range
of, say, 10 to 30cm. Is there such a thing?

A scissor jack or a small hydraulic jack might work but they both have
disadvantages:-

The scissor jack is 'wide', ideally I want something fairly slim.

A hydraulic jack has to be upright[ish].

That's certainly the right idea, thanks.

A Search term that may turn up something would be machinists jack,
Used in machine shops and thrown away by the ton over the past few
decades and now only available from a few suppliers.

Scaffolders use things called base jacks to provide a base on uneven
ground , you might find someting to suit using that term.
Might have to take a hacksaw to one.

If what you are trying to prop apart does not involve a lot of force on the prop then a quick release clamp with the fixed head reversed or a sash cramp the type with the detachable heads could be used in a similar way.

There certainly were mechanical bottle jacks about the same sort of
dimensions as a hydraulic one - maybe used from Ebay? Not sure I remember
seeing one that was as small as 100m closed, though.

It would help if you described the application... in particular the
load, conditions, duration of use etc.

However there are short underpinning jacks:

Well it's not just one application. However the most recent was to
hold up a bed while moving the floorboards underneath it. Other cases
I can think of (more horizontal ones) would be holding panels in place
in under seat cupboards while fixing them.

Light loads like that you could manage with an adjustable decking
pedestal,
various lengths and makes available.
One makers range here,

Or put decking pedestal into Ebay you'll get loads.

Many "trigger clamps" have reversible jaws, which will be OK for the bed
job and might work for the second one, with a bit of scrap timber as a
spacer.

e.g Screwfix part 86306. Key term is clamp *and spreader*

No, but it's tall, and wouldn't fit into a confined space like (say) a
bottle jack would. Your high lift jack is fine for things which can be
lifted from the side, but no use if it needs to (for example) spread
trench supports at the bottom of a trench.

I think you need a variety of them for the different situations,
a high lift jack, some underpinning jacks or something you
make yourself like an underpinning jack etc.

Er a 4 tonne underpinning jack to temporarily lift a bed a few cm?

Am I missing something here?

Can't you just pile some books up?!

Do people know what books are these days?
