Wubi86

1. * (chinese-forums.com) For 醫 for example I understand the AT but I don't understand the logic of D here at all. I think maybe the G is just the first horizontal stroke on the 酉? Anyway this is why I was hoping 五筆快打 would teach decomposition of traditional characters.

Because this character has many roots, the overall logic will be: Press the key for the first root, press the key for the second root, press the key for the third root, press the key for the final root.

Here is a breakdown of all the wubi roots in the character:

The first root is 匚 - A.
The second root is  - T
The third root is 大 - D (T and D put together gets you 矢)
The fourth root is 几 - M
The fifth root is 又 - C
The sixth root is 西 - S
and the final root is 一 G.

Why is the last root 一? Well, because there is no root for 酉. The S key only has the 西 root. This means that you still need to add a 一 to complete the character, thereby making G 一 the final root. Combined with what I mentioned above about typing the 1st, 2nd, 3rd and final root, it should now be clear why the final code is ATDG

2. * Although you can go character by character, you can also type in words and phrases. For two character words you type the first two shapes of each character. So, if you wanted to type 学习 you would IPNU. IP being the first two keys for 学, and NU being the first two keys for 习. There are further rules for 3, 4 and 4+ character phrases, and you can for example type a phrase like 中华人民共和国 just by typing KWWL.

3. 顶 would be SDM. S for the 丁, D for the top part, and M for the 贝. The thing to realise is that it's not necessarily radicals that are placed on the keys, it's just shapes. Sometimes this will be a radical, and sometimes only part of a radical. This is where practice comes in, so you can get a feel for how you need to combine shapes.
