What if the application I need to use is not a gtk+ application?
In Fedora 11 Ctrl+Shift+u + Unicode value works in all applications.

I need to enable "complex Asian layout" in OOo, but only in OOo. Yet I
also need to use Ctrl+Shift+u + Unicode value in OOo and other apps.

It would appear that someone has tried to create keyboard shortcuts for
some of the IPA characters. There are hundreds of thousands of possible
combinations of characters and diacritics. There could not possibly be
shortcuts for all of them.

In OOo I type Ctrl+Shift+u + Unicode value, followed by a space.

I cannot believe that the "IPA input method" is going to work. Suppose
I need to type a ɨ (barred i) with a combining diacritic for breathy
voice (Unicode 324), e.g., [ɨ̤]. Even an English syllabic r requires a
combining diacritic, e.g., [ɹ̩]. There are no fonts that contain all
the possible combinations of glyphs and combining diacritics as single
characters. It's not like typing French or German.

It appears that Fedora 11 is the last version of Fedora I will be able
to use.
