This is indeed confusing. Pressing Enter in an editor inserts a carriage return character rather than a line feed character. But pressing Ctrl + Enter is understood as <Cmd-j>. Never heard of this ascii mapping before. I don't see how this would be useful if you use a modern keyboard? I want a preference that makes my keyboard "work the same as in Windows" ;-)

This would be definitively useful!

Do you mean [enter] or [return]? ;-) "line feed" is actually CTRL-J, which is ASCII 10. If you do not happen do have the actual LF key on your keyboard, which is [enter].

http://www.physics.udel.edu/~watson/scen103/ascii.html
https://en.wikipedia.org/wiki/Enter_key

If you "duplicate all control/alt keys", that input will be translated to an actual [j] (ASCII 106) in the EventSensor.

This can be quite confusing. I would like to agree on a common programming model for keyboard events in Squeak. Too much platform-specific, low-level stuff leaks into the image. Even inconsistently on the same platform.

Hi Marcel,


thanks, maybe I will take a closer look at it :-)


So long, treat this as a note to myself:


Ctrl + Enter is also broken. It produces keystroke '<Cmd-j>' (106).


Best,

Christoph

Hi Christoph.

Try looking on squeak-dev for more information about user-input event processing and their quirks on various platforms.

In this case, it would help if you could find out the raw event data that arrives in Squeak through the EventSensor. It is an array filled with numbers. That a look at the class comment from EventSensor.

Considering control keys, also take a look at the mapping tables in TextEditor and all its subclasses.

We chose to not touch this issue in 5.3. We might want to harmonize that after the release.

I am in favor of programming against "#isControlKeyPressed and #keyCharacter ==" instead of actual control keycodes:

https://en.wikipedia.org/wiki/Control_character
http://www.physics.udel.edu/~watson/scen103/ascii.html

It would feel more object-oriented. But that's just my two cents. ;-) I rarely work in terminals. Anyway, one could easily map all control keycodes to higher-level object events in EventSensor or HandMorph.

Or maybe use [cmd]+[c] instead of [ctrl]+[c] anyway ... Hmmm....

Best,
Marcel

Ctrl + Insert - keystroke '<Cmd-e>'

Ctrl + PageUp - keystroke '<Cmd-k>'
Ctrl + PageDown - keystroke '<Cmd-l>' (108)
Only Ctrl + Delete works ...

Possibly related issue:

Ctrl + End generates an event like this: keystroke '<Cmd-d>' (100)

Hi all,


sorry to report to you another, though minor issue related to keyboard handling.


Steps to reproduce:

  *   Open a fresh trunk image on Windows
  *   turn off num lock (so that 4 works like arrowLeft)
  *   Go to any editor, such as workspace
  *   Press the number key 5

Expected behavior:
No character is inserted, as digits are turned off.

Actual behavior:
The quotes character (") is inserted.

Notes:
The issue already existed in Squeak 5.2, 4.6 and 3.9 (from my random tests).

Best,
Christoph
