I use KDE.
Now I'm trying KDE.
1. It took a lot of searching, but I found the ibus preferences. But
the gui is all in Chinese. How do I get it in English?
2. In KDE, when I'm editing a file (such as with (g)vi(m) or
LibreOffice), or otherwise entering text, how do I switch languages?
In Gnome, there's a small drop-down near the upper right corner of the
monitor.
