GUI editor for compose keys combinations

[pseudomonas]

Hi, I wonder if you kind people could give me some advice. I make heavy use of the system for entering non-ASCII characters whereby ComposeKey, char1, char2 gives another character, so (for instance ComposeKey, "!", "?" gives "‽").

I would like to know if there are any GUIs for editing these combinations, so I can easily add a few. I do in theory know how to do it by editing the config file, but this means lots of looking up hex codes and risking breaking things (it's quite easy to create combinations that make other characters unavailable).

Searching only gives me lots of advice on how to remap the ComposeKey (I'm happy with it remaining at its default of Shift-AltGr). Ubuntu packages seem to lack anything with the obvious keywords :-/

I don't know of a GUI editor, but I wanted to point out a vaguely-related thing (that I only know about because I know the guy who wrote it socially and we both have "funny letters" in the proper spellings of our names so got to talking about it once - there may be better tools out there for all I know since I don't actually use compose keys):

http://gtk-im-extra.sourceforge.net/imlatinplus-doc.html Latin Plus is a set of additional compose key sequences that might be useful depending on what you're doing, so if it meets your needs that might save you some time. It's focused around things that a predominantly English-speaking person using an American keyboard might need compose sequences for, particularly mathy stuff.

...I personally get non-keyboard characters in my documents by copying and pasting them in from various places, so I'm probably not all that helpful for your question.

I just use the US INTL keyboard layout.
It gives me all the accented characters I need to write in 4 languages (EN, ES, FR, PT), such as
é à ñ ö û ç, etc., and even stuff I don't use, like ß and þ
