Long press to switch keyboard not available on MIUI?

Mar 17, 2012
Sorry for the MIUI noob question, I feel dumb to ask something so basic, but I'm really stuck with the default MIUI English/Chinese keyboard.

I'm using default 3.3.15 English/Chinese ROM.
I used to be able to switch keyboard easily on other Android roms with a long press in any text field, but I can't reproduce that behaviour on MIUI.

I've installed ICS keyboard to be able to get other languages, but even if I set ICS keyboard as default, one I've changed to MIUI chinese/english keyboard, I've no way to switch back to ICS.
