[TxMt] Latex facilities

Hi all, I'm new to TextMate for Latex (and actually I'm new to Mac!) so excuse me if my question is "stupid". I've been searching for an answer to my question in the net for a lot but I didn't find anything. Before switching to TextMate I tried TexShop and I really like its Latex Panel (under the Window menu) because it helps you when you don't remember a mathematical symbol or something like that. My question is: does it exist something similar in TextMate? I like TextMate for the project option and the tab navigation but I miss the Latex panel and I can't prefer any of the 2 editors. What's your opinion? Thank you very much for your help, I really appreciate it. Michela
