Thanks for the feedback.
Sorry for asking, yes, it works, sorry for claiming that it did NOT work.
I think I just forgot to "Save" my preferences, I selected "enable" for those options and tried it in a Workspace and I think it didn't have any effect.
Because the feedback confirmed that the option *is* working, I tried again ...
And for some reason (maybe "Save" ?) it works now ...
I had noticed in Cuis-Smalltalk that they have this nice feature, and I wondered whether it also exists in Squeak.
So it does ... the feature 1) displays all assignments in Squeak code as left-arrows for me and 2) when I type in a Workspace it immediately displays an assignment as a left arrow.
I use a TrueType font that I have found on the net, which displays the underscore as a left-arrow.
I configured that font as my "code font" in the appearances menu.
As Tobias Pape points out special TrueType fonts are *not* required as Squeak has the machinery to swap the glyphs.
However there are a few fonts on the net that have old encodings for the glyphs for up-arrow and left-arrow.
However the solution that Tobias Pape mentions is better, as no special font, is then required.
Perhaps a small advantage of using a special font is that the special font, can also work in editors outside Squeak.
