tpb configuration
| key | config keyword |
|---|---|
| Access IBM or ThinkPad | THINKPAD |
| Home | HOME |
| Search | SEARCH |
| Favorites | FAVORITES |
| Reload | RELOAD |
| Abort | ABORT |
| Backward | BACKWARD |
| Forward | FORWARD |
| Fn | FN |
| FnSpace | CALLBACK (zoom on/off) |
| FnPageUp | CALLBACK (thinklight on/off) |
| FnF7 | CALLBACK (display lcd/crt/both) |
| FnF8 | CALLBACK (expand on/off) |
| FnHome | CALLBACK (brightness <percent>) |
| FnEnd | CALLBACK (brightness <percent>) |
| Volume up | CALLBACK (volume <percent>) |
| Volume down | CALLBACK (volume <percent>) |
| Volume 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 /etc/tpbrc.
For Debian users, tpb is started from /etc/X11/Xsession.d/90tpb.
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 or F21 |
| Forward | 233 | XF86Forward or F22 |
| Home | 178 | XF86HomePage |
| Search | 229 | XF86Search |
| 236 | XF86Mail | |
| Favorites | 230 | XF86AddFavorite or XF86Favorites |
| Reload | 231 | XF86Reload |
| Abort | 232 | XF86Stop |
| Fn | 227 | F35 |
(In case you want to use the browser keys in Firefox, you will have to assign the F21 and F22 or similar keysyms to 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.
Example Applications
Web Browsers
Firefox
(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 add the following lines within...
<key id="goBackTP" keycode="VK_F21" command="Browser:Back" /> <key id="goForwardTP" keycode="VK_F22" command="Browser:Forward" />
Now save the file and repackage the browser.jar archive...
# zip -rD0 browser.jar content/browser/
That's it.
Another interesting Page on Firefox is http://dqd.com/~mayoff/notes/thinkpad/dqdnavkeys/ It uses different key mappings (F19 resp. F20) but a ready .xpi is provided which is pretty comfortable.
Firefox and KDE
KDE provides Khotkeys. Get into the KDE system controls (kcontrol) and just assign keyboard inputs "Alt+Left" and "Alt+Right" to the two browser keys. That way, you don't need to mess around with the firefox internals. Maybe, you'll need to set up ~/.Xmodmap as described above in order to assign them the symbols XF86Back and XF86Forward.
Opera
However this isn't a simple configration file, you can set your browser manually.
Go to Tool > Settings > Mouse and keyboard > Keyboard settings > Edit > Browser Window. There add F21 - Back and F22 - Forward. Now you can surf using your TP keys ;-)
Window Managers
fvwm
To get the Backwards and Forwards keys to cycle through pages in the virtual desktop, add this to your ~/.fvwmrc:
Key XF86Back A A Scroll -100000 0 Key XF86Forward A A Scroll +100000 0
If you use multiple virtual desktops, you could instead use the keys to flip between them by using GotoDesk.
pekwm configuration
You can make the two browser keys switch workspaces in pekwm, by adding the following two lines to the ~/.pekwm/keys file:
KeyPress = "Mod1 XF86Back" { Actions = "GoToWorkspace prev" }
KeyPress = "Mod1 XF86Forward" { Actions = "GoToWorkspace next" }
pwm
Another example how to use these two keys to switch between pwm tabs. These two lines should be added to ~/.pwm/keys-default.conf or /etc/pwm/keys-default.conf:
kbind "Back", "switch_rot", -1 kbind "Forward", "switch_rot", 1
Other Uses
Console tools configuraton
To make the Forward and Backward keys useful in console, add this to your keymap (/etc/console/boottime.kmap.gz in Debian):
keycode 158 = Decr_Console keycode 159 = Incr_Console

| FOOTNOTES [Δ] |
- if there are more than one tool listed, one is sufficient
- 'full' means you can completely reassign any action to be triggered by the key, 'additional actions' means you can trigger actions in addition to the standard function of the key, which can not be changed.
