Marcel Taeumel uploaded a new version of Morphic to project The Trunk: http://source.squeak.org/trunk/Morphic-mt.1774.mcz
==================== Summary ====================
Name: Morphic-mt.1774 Author: mt Time: 18 June 2021, 8:42:44.573904 am UUID: 1e89964d-814b-4345-b3e6-fef6a4f54cc0 Ancestors: Morphic-mt.1773
Complements Kernel-mt.1403.
Adds #key to all keyboard events to be used as a cross-platform identifier (or object) for virtual keys. Works the same for keyUp, keyDown, and keystroke events.
Adds #keyCode, which is the low-level version of #key. For example, #keyCode would answer 29 while #key would answer "Character arrowRight" - an actual object that identifies the physically pressed key.
Use #key when implementing keyboard shortcuts. Feel free to check for modifiers or keyUp/Down/Stroke depending on your use case.
Note that this change relies on the fact that #keyDown will ALWAYS come before a #keystroke. Always. And that #keyDown events will carry the virtual key-code (or scan code), not a higher-level (Unicode) character for text input.
