I know the reason. But I need more discussion with karlt. Karl: I didn't send the alternative charCodes at AltGr(Win/Linux) and Alt(Mac) being pressed. However, that makes this regression. I think we need to send the alternative keys at that time on *all* platforms. How do you think?
Masayuki, so this issue is not OS X only? Then please set the OS field to all. Thanks.
I'm not sure this is XP bugs. Because I don't know win32 build has Ctrl+Alt+foo combination command, and Linux has Ctrl+AltGr+foo key combination. However, this is a design problem of the patch of bug 359638.

I think we need to send the > alternative keys at that time on *all* platforms. How do you think? I think the right thing to do depends on the platform. Mac: I'm not so familiar with Mac, but IIUC the Option key behaves similarly to AltGr when Command is not pressed, but it is also used with Command as a modifier for shortcuts. This results in similar problems to using the Shift key as a shortcut modifier. It can be unclear whether the Option key is used to select the character (consumed modifier e.g. ⌘[ on a Danish keyboard) or as a modifier for the shortcut (⌘⌥8). The problem is discussed here: http://sigpipe.macromates.com/2005/09/24/deciphering-an-nsevent/ There are some heuristics suggested there, but I guess they are not always going to be reliable. Was there ever a stage when both possibilities worked? (See bug 429211.) If so, I'd consider doing whatever is necessary to restore the previous behavior. If these didn't ever both work, then either we choose which to support, or (ideally I guess) we need to send a list of possible character/modifier combinations to try. Sending a list of characters with just one modifier set won't match both. (Perhaps some sort of possibly-ignore-alt-when-command-is-pressed logic can be worked, but the multiple modifier combinations feels more generic as that could handle Shift also.) Linux: On X11 AltGr is called ISO_Level3_Shift and corresponds to its own separate modifier (mod5). On that platform it is possible to press any combination of Alt/Ctrl/Meta together with either of the characters produced with or without AltGr. If the user has pressed AltGr then they mean the AltGr character, so the other character should not be sent. Windows: I hope an event with only the AltGr modifier doesn't look like any shortcut event. I'm assuming here that we don't use Ctrl-Alt together in any shortcuts. http://blogs.msdn.com/oldnewthing/archive/2004/03/29/101121.aspx I don't know whether it is possible to differentiate Ctrl-AltGr-char from AltGr-char. If not then I guess we can only assume AltGr-char, and it is not available for shortcuts. But perhaps they can be differentiated by recording the separate Ctrl-down event? If so then is there any reason why a non-AltGr character should be sent when AltGr is down?

Therefore, if AltGr is pressed we cannot fire the accelkey is only Alt or Ctrl commands...

That's what I was getting at, yes. But I suspect there must be a difference between AltGr and Ctrl+Alt because AltGr+Delete doesn't bring up the task manager. Whether that distinction is available to applications is the question. Looks like it is tricky to detect: http://cvsweb.xfree86.org/cvsweb/xc/programs/Xserver/hw/xwin/winkeybd.c?annotate=1.14#559 > Therefore, if AltGr is pressed we cannot fire > the accelkey is only Alt or Ctrl commands... Yes, we may need to live with that if there is no way to detect the difference. Even if there is a way, then we need not fix that right now.

I have a mistake. When the shift key is not pressed, only the first charCode is checked, sorry.

Attached patch Patch v1.0 for cocoa (obsolete) (deleted) — Splinter Review
This is for cocoa part. On Cocoa, even if option(alt) key is pressed, they send alternative chars too. When option key is pressed, sending following list. 1. unshiftedAltChar and shiftedAltChar 2. unshiftedChar and shiftedChar If option is not pressed, we are not sending the (1).

This looks like it is attempting to fix bug 306585 and bug 429211 (⌘[ when [ can only be produced when the Option key to be down). But outGeckoEvent->isAlt is set, so doesn't that mean that this event won't pass the modifier-match test in the handler anyway?

Oh, right...

On Mac, when Ctrl or Cmd is pressed, we should be able to ignore the Alt flag after all command handling was failed in current rules.

I posted the new patch to bug 306585. Because all parts are needed by the bug. But the patch also fixes this bug.
(In reply to comment #18) It'll take me some time to study that patch/bug. Can we do the part that fixes this bug separately, please, so that we can get this bug fixed sooner, as the part for this bug seems pretty simple.

This bug now comes back. Sorry, that is my regression. But the cause is really widget code. So, that is not related to bug 359638. So, *don't reopen this bug*. See bug 430419 for the new regression.
