How to get the meaning of a Mathematica symbol you don't know ?

Question

I would like to know how can I get help on a Mathematica symbol that I don't know ? There is often this case when I read some codes from forum or collegues. Thank you for your help.

Just type a question mark before the command and hit enter. Or highlight the symbol and hit F1 — Jason B., Aug 26 '15 at 08:22
minor correction: highlight (place the cursor on, or select, the symbol or term you're interested in) and press F1 (the function-1 key) on your keyboard. Also note that the Help documentation built into Mathematica is excellent (allows searching on symbols, too), and that it is also completely reproduced online reference.wolfram.com — TransferOrbit, Aug 26 '15 at 08:24

I am sorely tempted to close this as "easily found in the documentation"… — J. M.'s missing motivation, Aug 26 '15 at 09:07
@Guesswhoitis. But what if you can't find the documentation? :-D — LLlAMnYP, Aug 26 '15 at 11:35
More seriously, there's a fantastic package here: http://mathematica.stackexchange.com/a/15948/26956 although I don't think, this is exactly as deep as the OP wanted to go (or rather, vice-versa). — LLlAMnYP, Aug 26 '15 at 11:48
note a "symbol that I don't know" isn't necessarily a documented thing so F1 may not work. — george2079, Aug 26 '15 at 15:46

In{1};= ?FindFit [Shift+Enter]

Then click the >>> at the bottom to expand the text. Placing the MMA command after the ? will give you the description and usage.
