standart events for hotkeys?

standart events for hotkeys?

[Michal Semler (volny.cz)]

Hi guys,

I have a question related to keyboard and hotkeys.

Does any standart exist for hotkeys and their returned events?
I have 2 keyboards with hotkeys, one on laptop (acerhk operated) and one 
wireless (BlueZ bthid operated) and both returns different codes in xev when 
same keys are pressed

mail
browser
etc.

Maybe these should be standardised in all drivers? Can we start same kind of 
list, where will be all events stored and then translated by all drivers the 
same?

Now users can't use one hotkeys configuration on different keyboards so these 
could be renamed to hellkeys :)

Your opinions?

Michal

X already has codes for many of the hotkeys defined in. They have 
names like XF86AudioMute etc. The inet rules define the proper 
scancode -> keycode assignment for X for many keyboards modules.

Yes, I think it would be an interesting idea to have some kind of 
standardization of this for the Linux kernel as well, but before 
thinking about this (or at the same time) it would be nice if we 
could fix the bug in the atkbd driver that makes some of the hotkeys 
that use extended keycodes inaccessible or "shifty".

I believe vojtech already has codes assigned to keys like those.

Hmmm and all the drivers has to use them?

yes,

and this is what I mean. We should start project collecting this. As PCI cards 
list for example.

That is my opinion. And yours?

There are as many e-mail keys codes as there are e-mail programs.  And 
I'm sure there is over lap, where one keyboard's e-mail key, generates 
the same code as another's web browser key.  Also it doesn't really 
matter what a key is labeled, it could be assigned to anything.

What there should be is a program that is configurable, that says when 
you see this key event, do this.  And such programs do exist, for 
example the GNOME desktop has ACME.

All that has to be done is make sure the kernel passes this codes, and 
the user space program can gather them.  That seems to be working now.

Hi, 

this isn't true, coz when somebody (me) has two keyboards and both returns 
another scan codes for one labeled key, so you can't use hotkeys or Khotkeys 
or another one.

It is because when you pres e-mail key, in one keyboard it returns one 
scancode and run for example will run kmail, but when you press it on second 
keyboard and it returns another scancode, it runs and it will run xterm... :(

So we need wrapper which will translate scancodes from all keyboards to 
standart scancodes and then it can be used with hotkeys and will work with 
all keyboards and will start kmail everytime on every of keyboards.

See below.

Well, this is a secondary matter.

Recent X versions have keysyms for the multimedia keys, with 
names like XF86AudioPlay, XF86VolumeUp etc. In your keyboard 
setup you can choose an inet module specific for your 
multimedia keyboard (provided it's supported) and the scancodes 
will be converted to the correct keycodes with the attached 
"multimedia" keysyms, which you can then map to the whatever 
action you might want.

Or rather not, due to the RAW mode emulation (see also my posts 
on my problems with configuring the multimedia keys of my Dell 
Inspiron 8200 with the 2.6 kernels).
