[Uim] Possible to switch input method by hotkey or menu?

[Yaohan Chen]

Hello,

Is it possible to have a hotkey to cycle through the enabled input methods, or 
a menu in the helper toolbar or systray icon to (mostly) replace the 
im-switcher windows? I type three languages, most usually English, then 
sometimes Japanese, and occasionally Chinese. While I could set the Japanese 
input method to be alternative, it's inconvenient to open the im-switcher and 
select the Chinese input method every time.
