Hi all!
Please find attached an updated changeset with a "KeyboardExerciser" to help you test and inspect the incoming keyboard events. You can find it also in the parts bin nearby the "ClickExerciser".
The visuals are supposed to look platform-specific. However, the event data contains information to make your application work across platforms. See KeyboardEvent >> #checkCommandKey for more explanations.
Try [CTRL]+[C] for keyStroke, keyDown, and keyUp.
Note that the visuals might not look right for keyUp and keyDown events due to missing lookup tables for the raw, platform-specific key codes. On my machine, for example, [,] and [.] and [-] look odd:
Nothing to worry about because all keyboard shortcuts in Squeak use keyStroke events at the moment.
Best,
Marcel

Hi all!
Please find attached a changeset that improves the cross-platform base for keystroke events. Please try it out and take a look at it. Report issues ASAP so that I can merge it into Trunk soon.
Thanks to Tom (tobe), the new promising idea is to replace the existing attempt:
Duplicate all control and alt keys
Duplicate control and alt keys
Swap control and alt keys
With the following preferences:
[X] Map ASCII control characters to printable characters
- Default is TRUE
- Only affects events that have the CONTROL modifier set (e.g. CTRL+J)
- Rather application-specific than platform-specific
[X] Map CONTROL keys to COMMAND keys
- Checked at image start-up
- TRUE on Windows/Linux
- FALSE on macOS
[X] Map ALT keys to OPTION keys
- Checked at image start-up
- TRUE on Windows/Linux
- FALSE on macOS (bc. ALT==CMD on recent Linux/Windows VMs)
Please take a look at KeyboardEvent >> #checkCommandKey to learn about the fundamental trade-off we have solved.
Please try out your preferred applications. Feel free to add logging to HandMorph >> #logEvent: for more convenient testing:
(anEvent isKeyboard and: [anEvent isKeystroke])
ifTrue: [Transcript showln: anEvent].
Thanks!
Best,
Marcel (and Tom)
