zoom key is not working (microsoft ergonomic keyboard 7000)

[Adriano Mitre]

The zoom key (scroll) of microsoft ergonomic keyboard is not working, both for ergonomic desktop 7000 (wireless) and ergonomic keyboard 4000 (wired). When the key (scroll) is "pressed" not even an event is seen on xev, suggesting that it is problem with the lower level.

This also doesn't work for me.

I have a similar keyboard (the wired 4000), which has a simple 'zoom' toggle. Like the original poster, I see nothing on xev when pressing the keys.

Personally I don't care that this doesn't work. I'm not ever sure what 'Zoom' would mean, since one nornally doesn't zoom on a desktop. If it was to scroll instead, that would be helpful.

Zoom is what you get with Windows Key + mouse scroll.

Anyway, if xev detected some event it could be remapped to scroll, for
instance.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in udev, since it appears X is not getting a keypress at all.

When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Please exercise the steps at https://wiki.ubuntu.com/Hotkeys/Troubleshooting to determine at which level your hotkey problems occur, and attach the collected information. Thanks!

It's very likely that the Linux kernel/udev actually know the key, but it's a known limitation to X that KEY_ZOOM cannot be used in X (since it's greater than 255). But let's check if the udev keymaps are right in any case.

[Adriano Mitre (adriano-mitre)]

I have carried out the trial, but no keypress event is generated when zoom
key is scrolled up or down.
Just like firstly reported.

Did you try all input devices with keymap -i? It's hard to predict on
which one it will appear.

> Just like firstly reported.

You originally said that you tested with xev. But it is known that
X.org cannot handle "zoom" keyboard events.

Hi.
I did not understand what tests should I do. How can I test "keymap -i"?
I tried "sudo apt-get install keymap" and "apt-file search keymap" but could
not figure out what command should I use.
Thanks in advance.

It's described in /usr/share/doc/udev/README.keymap.txt.gz (one of the points on that wiki page).

[Adriano Mitre (adriano-mitre)]

Although
$ sudo /lib/udev/findkeyboards
produces only
USB keyboard: input/event4
And all "regular" keys generate events in
$ sudo /lib/udev/keymap -i input/event4
Some special keys such do not generate events.
However, they are present when event5 (which is not listed as an option by
findkeyboards, though) is used instead of event4. Not that the zoom keys
generate events!
$ sudo /lib/udev/keymap -i input/event5
scan code: 0xC0192 key code: calc
scan code: 0xC00CD key code: playpause
scan code: 0xC00E9 key code: volumeup
scan code: 0xC00EA key code: volumedown
*scan code: 0xC022D key code: zoomin*
*scan code: 0xC022E key code: zoomout*
Now we are talking, right? Thanks!

Ah, indeed. So that confirms my suspicion in comment 4: the keys are workign from a kernel/udev perspective, but X.org can't deal with them, see bug 313514.

[Adriano Mitre (adriano-mitre)]

The numbers udev/keymap gives for keys like calc are also > 255 but are
still recognized by X.

How I discover which numbers are available to remap using rawkeybind?

KEY_CALC has value 140, so it's < 255.

Sorry, I don't know this tool. keymap -i will tell you the key code,
but if you need a complete list, /usr/include/linux/input.h is the
definitive source.

Here's a work-around for remapping zoom to page-up/down for this keyboard:
