Note: If you don't want to assign a special "Multi" key, you can use the default X11 key binding of <Ctrl-Shift-T> (providing the application you're using doesn't already use it for something else), and skip straight to the next section: Using the "Multi" Key.
First you need to enable a "Multi" key. I use Caps Lock, because a long time ago I discovered that Caps Lock was more useful disabled than enabled. Several of my colleagues popped the keycap off, but I prefered a software solution and turned to xmodmap.
Place the following lines in ~/.Xmodmap:
! clear caps lock & make it into the multi key remove lock = Caps_Lock keycode 66 = Multi_key
(If you just want to disable Caps Lock just put the "remove" line in).
You can check the keycode of the Caps Lock key using the xev application (or if you want use a different key as the "Multi" key like the Windows keys or the Menu key).
Some X11 environments will read ~/.Xmodmap when you start them up, others will need to have the following line added to the start-up file (often ~/.xsession):
xmodmap $HOME/.Xmodmap
Or you can just type it into a terminal to enable it immediately.
You can now use the "Multi" key to generate special characters in X11, for example:
Key Sequence | Character | |
---|---|---|
Multi a " | ä | (adiaeresis) |
Multi c , | ç | (ccedilla) |
Multi e ' | é | (eacute) |
Multi i ^ | î | (icurcumflex) |
Multi n ~ | ñ | (ntilde) |
Multi o / | ø | (oslash) |
Multi u ` | ù | (ugrave) |
Multi Y = | ¥ | (yen) |
Multi 3 4 | ¾ | (threequarters) |
Multi ^ 0 | ° | (degree) |
For a full list of key sequences and the characters they produce see the file locale/iso8859-1/Compose on your system (usually under /usr/X11R6/lib/X11 or /usr/share/X11).
