Meaning of keycodes unclear

Meaning of keycodes unclear

[Florian Festi]

I am looking for the meaning of the following key codes as #defined in 
include/linux/input.h. I need to know what hardware produces the keycode 
and what happens/should happen when the corresponding key is pressed.

KEY_AB
KEY_ANGLE
KEY_ARCHIVE
KEY_CONNECT
KEY_DIGITS
KEY_MACRO
KEY_ISO
KEY_LIST
KEY_POWER2
KEY_QUESTION
KEY_TEEN      # 1- ???
KEY_TWEN      # 2- ???
KEY_RED, KEY_GREEN, KEY_YELLOW, KEY_BLUE  # Video text navigation?

I am currently trying to make all special keys just work by fixing the 
whole keyboard/input stack from the kernel up to the desktop 
environments. On part of this effort is to complete the mappings applied 
to the keys during their way up.

TIA

Macro key was present on some old keyboards. It allowed macro definitions.

Yep. Very common on remote controls.

Yes.

I'm guessing it's "A/B" key on (TV) remote control, e.g. to switch between
two input sources

probably DVD or set-top-box remote control key to switch
between alternate video streams (video viewing angle / camera position)

might be used on TV remote control for "channel list"

these are really application-defined multi-purpose keys,
not just limited to teletext; present on every European
TV or set-top-box remote control

I presume this is the macro defining key, used on keyboards like the 
Gateway102. I thought it was handled internally and didn't send a 
keycode, but other keyboards had/have that feature as well.

Used G102 for application work, had the function keys both next-to and 
above the alpha keys, so you could bind up to 48 application functions 
and still have function keys as other things wanted them.

Hope that answers your question.

Thanks for all you comments! They helped a lot.
The meaning for some keycodes is still missing, though:

* KEY_ARCHIVE, KEY_FILE, KEY_DIRECTORY - What's the difference here?
* KEY_DIGITS
* KEY_ISO - somehow related to KEY_KATAKANAHIRAGANA ??? (mapped to same 
scancode in rawmode emulation)
* KEY_MODE
* KEY_QUESTION - what's the difference to KEY_INFO and KEY_SEARCH?
* KEY_SCREEN - switch between 4:3 and 16:9 ???
