ibm-acpi events
| key | event |
|---|---|

| Fn-F4 | ibm/hotkey HKEY 00000080 00001004 |
| Fn-F12 | ibm/hotkey HKEY 00000080 0000100c |

tpb configuration
| key | config keyword |
|---|---|
| Access IBM | THINKPAD |
| Home | HOME |
| Search | SEARCH |
| Favorites | FAVORITES |
| Reload | RELOAD |
| Abort | ABORT |
| Backward | BACKWARD |
| Forward | FORWARD |
| Fn | FN |
| Fn-Space | CALLBACK (zoom on/off) |
| Fn-PageUp | CALLBACK (thinklight on/off) |
| Fn-F7 | CALLBACK (display lcd/crt/both) |
| Fn-F8 | CALLBACK (expand on/off) |
| Fn-PageUp | CALLBACK (brightness <percent>) |
| Fn-PageDown | CALLBACK (brightness <percent>) |
| Volume up | CALLBACK (volume <percent>) |
| Volume down | CALLBACK (volume <percent>) |
| Vokume mute | CALLBACK (mute on/off) |
To all parameter keywords should be assigned the full path to the executables supposed to be started on key press. The exectable provided for the CALLBACK keyword should take the parameters given in parentheses and act according to them. If you want to use xmodmap for the HOME, SEARCH, MAIL, FAVORITES, RELOAD, ABORT, BACKWARD, FORWARD and FN keys you should provide a XEVENTS=off in your tpbrc.
xmodmap configuration
xmodmap enables you to edit the modifier map and keymap tables that are used to translate keycodes into keysyms. Understood? Well, basically it allows you to give the X server a dictionary for the translation of keycodes like "97" into more human readable synonyms like "Home". This way xmodmap allows you to make the special keys of your keyboard known to X applications.
Usually you should write your keycode-keysym associations into the file ~/.Xmodmap. This file is usually read by the X session startup scripts of your system, so that the mappings automatically get included everytime you run the X server.
The ~/.Xmodmap lines for our purpose are in the form of
keycode <keycode> = <keysym>
The following table shows the keycodes generated by the Thinkpad special keys and sensible keysyms to assign them to.
| key | keycode | keysym |
|---|---|---|
| Backward | 234 | XF86Back |
| Forward | 233 | XF86Forward |
| Home | 178 | XF86HomePage |
| Search | 229 | XF86Search |
| 236 | XF86Mail | |
| Favorites | 230 | XF86Favorites |
| Reload | 231 | XF86Reload |
| Abort | 232 | XF86Stop |
(Ofcourse you could also use Fxx keysyms as suggested by a lot of people, but if X offers special keysyms for internet keyboards, why not use them?)
Note: if you are running tpb you might need to add the line XEVENTS=off into your tpbrc to stop it from grabbing the key events and allow them to get through to X instead.
firefox configuration
(First of all thanks go to Ryan Barrett for writing the little howto on his blog.)
To have firefox make use of the browser keys you need to modify one of its files.
To do this you will first need to extract it from the browser.jar archive. Do...
$ cd <firefox-directory>/chrome $ unzip browser.jar
The file of interest is content/browser/browser.xul. Edit it...
$ vi content/browser/browser.xul
Look for the <keyset id="mainKeyset"> section and in there for the lines...
<key id="goBackKb" keycode="VK_LEFT" command="Browser:Back" modifiers="alt"/> <key id="goForwardKb" keycode="VK_RIGHT" command="Browser:Forward" modifiers="alt"/>
Add the following two lines immidiately after them
<key id="goBackKb" keycode="VK_XF86Back" command="Browser:Back"/> <key id="goForwardKb" keycode="VK_XF86Forward" command="Browser:Forward"/>
No save the file and repackage the browser.jar archive...
$ zip -rD0 browser.jar content/browser/
That's it.
pekwm configuration
This is just a small example of what else you can do with your extra keys.
I configured the two browser keys of my T41p to switch workspaces with pekwm, by adding the following two lines to the .pekwm/keys file:
KeyPress = "Mod1 XF86Back" { Actions = "GoToWorkspace prev" }
KeyPress = "Mod1 XF86Forward" { Actions = "GoToWorkspace next" }
(As you can see the XF86..... keysyms are just as universally usable as any others.)
