I added an issue:

15541 windows vm does not distinguish between ctrl+a and ctrl+home

with a proposed solution:

add $a-1 to the utf32Code field of the event struct, if the keyevent is a keystroke and the ctrl flag is set

what do you think?

There is an end key in many keyboards, but some others do not have it. Can you (or better, How would you) have ctrl+end in keyboards that doesn't?

Some VMs hardcoded that Ctrl+a = ctrl+home and Ctrl+d = Ctrl+end because that's how old terminals work... Now, why have hardcoded ctrl+a = ctrl + home, if you can just add a keybinding to ctrl + a?

Hi

hasSpecialCTRLKeyValue was extracted by me when I hack keybindings to make ctrl+home and ctrl+end working. Like you I was very��surprised��by such keyboard events crappy state.

So, having ctrl+end and ctrl+d working at the same time is not possible?

There is a problem in the whole keyboard events: they treat keys as characters and vice versa. And that's not always true:��

��- the backspace key is a key, but currently the image interprets it as a character because we only use keypress events in general.

��- the shift key is a key, and since current image does not use keyup nor keydown, we cannot know if JUST a shift is pressed normally.

I don't know anything about event handling, but I once had a look at Character constants, and found this:

Character class>>#home
�� ^ self value: 1

How about that ?? This is wrong IMHO, ASCII / Unicode value 1 is SOH (Start of header), sometimes typed as CTRL-A. And there are other strange constants like that there.

ctrl+a has the same strange behavior as ctrl+d
ctrl+a -> ctrl+home
ctrl+d -> ctrl+end

look at KeyboardEvent>>#hasSpecialCTRLKeyValue

I am not exactly sure why it is handled that way.
Replace the method with

hasSpecialCTRLKeyValue
������ ^ self controlKeyPressed and: [ keyValue <= 26 ]

now, ctr+a and ctr+d working as expected.
But I don't know about the side-effects.
