Eng:List of Scratch Morphs

Translate: - English 

Scratch Morphs are what the visible objects in Squeak Smalltalk are called. The term comes from the graphics system used called Morphic. Morphs are like sprites in a way; in fact, at some level of abstraction, a sprite is an instance of a SpriteMorph. Many morphs have their own unique Alt-Click Options.

This is the complete list of morphs (in the world menu) by category, which also explains each morph. It will also give the list of options exclusive to morphs when the morph is alt clicked/right clicked and "Menu for me" (the red circle) is selected.
