User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3) Gecko/20030312 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3) Gecko/20030312 The fix for Bug 69565 introduced this (yet undocumented) keyboard shortcut into Mozilla. The shortcut works fine on current Mozilla builds for Linux, OS/2 and Mac OS X, but it is broken on Windows (although Ctrl + non-NumPad 0 does work). Reproducible: Always Steps to Reproduce: 1. Press Ctrl++ or Ctrl+- to change the Text Zoom 2. Press Ctrl+NumPad 0 to restore the text to its original size (100%) Actual Results: Nothing happens. Expected Results: The text should be restored to 100% This bug happens with 1.2.1, throughout the 1.3 branch as well as with 1.4a (20030318)

Linux & OS/2 are not broken. all->not
Status: UNCONFIRMED → NEW

Actually, on OS/2 it is *partly* broken - the NumLock has to be on in order for this shortcut to work... BTW, aren't keyboard shortcuts supposed to be implemented using scan-codes rather than characters? Prog.
I can NOT reset zoom to 100% by hitting "ctrl+numeric keypad 0" on Linux. That was why i changed OS: to ALL. Trying again. Current trunk CVS; Linux.
OS: Windows 2000 → All
R, I didn't see your change, thinking only the original report was broken, as you failed to confirm when you changed. On Linux Mandrake 9.0 KDE 2003031714 it works with NUM on, and I didn't try it with NUM off, same as OS/2 2003031712 as described on comment 2. I never use any PC with NUM off.
Yet more confusion: Both Ctrl+NumPad 0 and Ctrl+0 are broken on the official Mozilla 1.3-final for BeOS (downloaded from mozilla.org) Oddly enough, both shortcuts work perfectly on Sergei Dolgov's Mozilla 1.3b (20030216) variant (aka Stripzilla; downloaded from BeShare P2P network) Prog.
Confirmed with Linux RH 8.0 and 1.3-final. Exactly the same case as with OS/2 - you can't reset zoom if NumLock is off. Prog.
Correction: you can't reset zoom using Ctrl+NumPad 0 if NumLock is off.
On W98 in 1.4rc2 you can't switch among windows with numpad either. Ctrl+NUM0, Ctrl+NUM1, Ctrl+NUM2, Ctrl+NUM4, Ctrl+NUM5 & Ctrl+NUM6 all do nothing, whether NUM is on or off.
*** Bug 216710 has been marked as a duplicate of this bug. ***
With NumLock off the number pad keys actually generate cursor keycodes so 0 is Insert and Ctrl+Num0 will paste (windows compatibility shortcut). With NumLock on the number pad keys generate VK_NUMPAD keycodes. Windows will translate these to ASCII numbers, but only if they are unmodified. We could manually translate Ctrl+ and Shift+ keycodes to ASCII numbers but we'd have to avoid Alt+ because they're used for extended character generation.

CC'ing Blake Ross and Gavin Sharp since they fixed bug 174854.

No, bug 256683 is specifically for help viewer. They just don't have that shortcut key hooked up at all. This is about the Numpad 0 not returning the same keycode as the regular 0. See comment 10.
would take a patch for this but won't hold. renominate if a patch appears

We should make this ctrl+= and not ctrl++. That's thre real behavior, at least on windows, and it should clear up the confusion about the number pad. Blake said he was going to change that with his recent menu changes for this feature.
Simple switch, and it seems like this is already in the help documentation (they have "Ctrl+= (plus sign)" listed as the shortcut).

Ctrl+= doesn't work for example Finnish or German keyboard. On Finnish keyboard = is on top of 0 and + is unshifted next to 0. Ctrl++ works for all keyboards I've tested. Having the shortcut listed as Ctrl+= would confuse a lot of people with non-us keyboards.

Blake > said he was going to change that with his recent menu changes for this > feature. With all due respect, this doesn't make logical sense. Ctrl+- is effectively "minusing" (decreasing) the size of the text, while Ctrl++ is effectively "plussing" (increasing) the size of the text. Ctrl+= doesn't make sense in this manner. Now, if you're going to argue that that logic is hair-brained when one realizes that "+" is only an unmodified key on the Numpad (not used so much, esp. on keyboards) but not on the main keyboard (probably used more, esp. since most other shortcuts are for letters, which are in the main keyboard), then you have a point. If you really it's a good idea to emphasize = over +, do what you want. Is this bug for Seamonkey or Firefox? The bug is in the Seamonkey component, but the patch is for Firefox. If you're fixing for Seamonkey, please patch Seamonkey.

All these patches do is change the default accesskay, so the menu shows "Ctrl+=". These patches do not turn off Ctrl++. Both of those patches apply to trunk for FF and Seamonkey respectively.

Blake > said he was going to change that with his recent menu changes for this feature. We really shouldn't. I fully agree with Jeff Walden that +/- have a sense of bigger/smaller, while =/- do not. Instead of moving the goal posts, how about fixing this bug? A reminder: "Ctrl+NumPad 0 does not restore Text Zoom to 100%". Prog.
(In reply to comment #20) > All these patches do is change the default accesskay, so the menu shows > "Ctrl+=". These patches do not turn off Ctrl++. Yes, and that's not good. Ctrl+= doesn't work for all keyboards. I also fully agree that +/- is meaningful while =/- isn't.
Ere, I understand your opposition to the switch, I just made the patch in response to Asa's comment. I also noted that, with that patch, people using keyboards that don't work with Ctrl+= would still be able to use Ctrl++. I agree that this is not the best solution, but it is the easiest solution. If someone could implement the solution mentioned by Neil in comment 10, we'd be much better off.
Well, I believe we could special case at least ctrl-numpad keys (wouldn't be the first special case at least for Windows' keyboard handling). I'd rather go that way although I still don't really like translating numpad 0 to 0 when numlock isn't on. I can try that on Windows, any takers for other platforms?
I tried but couldn't find a way to see when numpad 0 is pressed and numlock is off. Windows returns VK_INSERT, which is indistinguishable from the normal insert key.
This is a pretty important issue for us with European "numbers above" keyboards. Basically, if the user wants to reset the text, he'll try to pull off Ctrl+0. Here's the problem, on French/Belgian keyboards (those are the ones I know of), to make a 0 (or any other number) you need to Shift the key (for example, on my keyboard, Shift+à = 0), if you get what I mean. This lead to me initially trying to Ctrl+Shift+à, which failed. Ctrl+à works, and the problem is obvious. It would really be useful if the Numpad 0 worked, since it's a very accessible key, and doesn't require the additional thought process of guessing whether you need to Shift a key or not. Requesting blocking-aviary1.0, this is a real usability issue for users with AZERTY keyboards.

I just discovered that this shortcut does work in recent builds for Windows when NumLock is On (just like it always did in Linux and OS/2). Changing summary accordingly. cusser.bugs@cusser.net, please read comment #29 before setting the blocking flag. This bug has no working patch. Prog.

Would something like this be an acceptable solution? (other platform/widget code need similar changes of course)
