Kanji? I have no Idea how to use. Help!!!

How do you setup the kanji so they can be used as you type? that is, while you are writing in hiragana in the code, it will print kanji. I know it can be done, because the comments in another code was in kanji.

The only way is to copy and paste them from another file. I believe SYS/KANJITBL has a nice list.

Really? I that sounds like it would take way too much time though. I tried looking through, and some of the characters are so squished I can't recognize them. And they are hard to find. when I want the character for kuchi, I looked under ku/gu, but it turned out to be found in kou. Then how do I find the characters that have like ten readings as in shita for kudasai?
