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.

  • $\begingroup$ Just type a question mark before the command and hit enter. Or highlight the symbol and hit F1 $\endgroup$

  • $\begingroup$ 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 $\endgroup$ Aug 26, 2015 at 8:24

    $\begingroup$ I am sorely tempted to close this as "easily found in the documentation"… $\endgroup$ Aug 26, 2015 at 9:07

    $\begingroup$ More seriously, there's a fantastic package here: 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). $\endgroup$
