Having recently moved to Linux/Ubuntu, I'm looking for a good editor, and GNU Emacs seems to fit the bill.

One thing I want from a text editor is the ability to handle Unicode Input Method Editors in a "normal way", across the board. For Ubuntu, the "normal way" is via IBus.
However, emacs does not support IBus "off the shelf".

I found a launchpad project: IBus client for GNU Emacs: ibus-el.

I've installed ibus-el and set it up as per the Customize section of this emacswiki IBusMode page. I included the suggested "toggle" keybinding: ;; Use s-SPC to toggle input status

It seems to have installed okay, but I have no idea how to invoke IBus and switch IMEs.

s-SPC doesn't fire up the IBus language panel... I'm stuck :( ...so close, yet so far....

Here are the startup *messages*
