Traditionally in Squeak, you could cycle through Morphs in either direction -
from the topmost (e.g. a TextMorph in the Window) which is Alt-Shift-click
on Mac, or bottom most parent (e.g. from the Window) which on Mac is
Alt-click. Some people found the non-Shift version troublesome because they
accidentally brought up halos.

So in Pharo by default, you can Alt-click. You can also re-enable the
Alt-Shift-click direction via the settings browser: (World
Menu->System->Settings). Text search on halos and then enable "Cycle both
directions"
