How to list all currently available compose key combinations

compose-keykeyboard-layoutx11

Is there some way to inspect the state of X to get exactly and only a list of compose key shortcuts and what they map to, either as literal keys, for example:

aa å
88 ∞

or as glyph names, for example:

aa Latin Small Letter A with ring above
88 Infinity

or, ideally, a combination.

I'm not using GNOME.

After reading the links in the accepted answer I ended up with the following command:

less "/usr/share/X11/locale/$(grep --max-count=1 "${LANG%.*}.UTF-8\$" /usr/share/X11/locale/locale.dir | cut --delimiter=/ --fields 1)/Compose"

Not exactly. If you are talking about X alone, you can look at the compose tables. However, some people want to know this about GNOME without making a distinction.

The Gtk Compose Table started off as X compose tables, but has diverged (as well as providing some new codes). According to the documentation, that information is built into the program.
For X, as mentioned, that information is in the Compose tables as discussed in Where can I find the full list of Compose combinations for my locale? and FULL LIST of Entering Special Characters with Compose Key?.

Original answer:

You may need to log out and in again, since your personal configuration files are read when logging in.

(There may also be some way to activate it without logging out and in again, but I'm not familiar with this specific configuration file.)

You can find the compose table used by your system at the same place programs do: it's a text file. To locate it, you can run something like

strace xterm -e true 2>&1 | grep -i compose

For example, the relevant lines on Debian wheezy are:

open("/home/gilles/.XCompose", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/share/X11/locale/compose.dir", O_RDONLY) = 5
open("/usr/share/X11/locale/en_US.UTF-8/Compose", O_RDONLY) = 5

This demonstrates several things:

To define your own table, put it in the file ~/.XCompose. Actually, you can override this location by setting the environment variable XCOMPOSEFILE.
The location of the system table is listed in /usr/share/X11/locale/compose.dir. This file can list different tables for different locales.

ComposeFU is a recent addition, the corresponding character is itself a recent addition to Unicode.
