Over the past few days I've gotten used to the Shuangpin layout. 自然码 to be specific, and I found it to be pretty good. But now I've come across a situation, where I don't know how to type it. And after taking a look at all the different Shuangpin layouts, it seems to me, they all share this property:
They don't have a key for the "zero initial"! So how do you type words like 昂 (ang), or 恩 (en)?
I'm specifically looking for the Ziranma layout, but I'd be interested in a general answer as well.
