Pronunciation - several issues

The recent thread about "to" and "re" reminds me of some questions about pronunciation, i already have for a very long time.

Is じ pronounced in any way differently from ち ? Is it "dshi" and "tshi"?

How do you pronounce the doubled consonant in いっしょに (isshoni) and in ホッチキス (hocchikisu)? Is it pronounced "is-shoni" and "hot-chikisu", or "ish-shoni" and "hoch-chikisu"?

When do you use つ゛instead of ず and is it pronounced differently?

じ Which one is "Ji" ぢ | Japan Forum

and isshoni, hocchikisu.

I'm also still wondering how to make the つ゛display on a Japanese keyboard, so if anyone can explain it simply please do....

Wait, are you talking about IME?

If so, just type in "du."

If you're talking about a regular Japanese keyboard, I can't help you there. Sorry ^^;

Thanks! Actually I wanted to know both, but it's probably the same.
