what is that up side arrow before the number 10 in the constant method instance below?

Question

To make it clear and concise:

1. What is it?
2. Why is it there?
3. How to type it with a normal Keyboard?
4. Thanks!

Answer 1

It's ^ symbol. :) A return statement in smalltalk.

I don't know if it's default listing's feature in latex, but upward arrow is being used of ^.

On normal keyboard you can type this symbol by pressing Shift + 6

Answer 2

Just for the record, in old versions of Pharo, the ^ character was printed as an "up arrow". So, as Yuriy says type ^ to get the "up arrow" return.

That behavior does not exist any more in latest versions of Pharo: ^ is printed as ^.
