Default Slow Down, Speed up

The use of ailerons to rock the wings to indicate too slow was discontinued
in the UK in the 1960s, it was thought to be responsible for gliders
spinning on the wire. The appropriate action is to lower the nose. A
switched on winch driver will spot this and speed up, if he can. If you
get a dozy one, or there is a problem then the action is to treat as a
failure and release.
Too fast, yaw with rudder. I have always wondered about high yaw rates
with high angle of attack and wing loading, even if the indicated speed is
"high", but that is still the "official" procedure in the UK.
Yaw to indicate too slow, seems a quick way to get back down on the ground
to me.

cursor is to lower the nose and unload the airframe.

In Denmark, it's exactly the opposite...

Yaw/Rudder for speed up, Roll/Ailerons for slow down and they are the
same in Germany as far as I know.


Interesting. I remember the US signals by remembering that if I'm slow
on the edge of a stall the last thing I want to do is aggressive
ruddering.
