# Key to get help about current function

I know you can hit F1 to pop up the documentation center, and then type the name of a function and search for it.

I'd like to know if there's a key that just pops up the help page of the function the cursor is in right now.

For instance, when writing Integrate[, sometimes I forget the right syntax for it, so I just want to immediately see the help page for it without having to manually search for it.

You can right click the function and select 'Get Help' –  ssch Dec 3 '12 at 12:06
Welcome to Mathematica.SE! I suggest the following: 1) As you receive help, try to give it too, by answering questions in your area of expertise. 2) Read the FAQs! 3) When you see good Q&A, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. ALSO, remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign` –  Vitaliy Kaurov Dec 3 '12 at 13:22
@VitaliyKaurov Don't worry, I will. I just like giving it a day or so before accepting an answer. –  Malabarba Dec 3 '12 at 13:25

It is the same F1 key. If the cursor is anywhere in the name of the function adjacent to any function-name letter, then pressing F1 will bring the corresponding function documentation page.

Mathematica 9 Context-Sensitive Input Assistant (or see this video) provide a set of useful options. For example this will appear as you type and clicking red-circled icon will also bring corresponding function documentation article:

BTW @ChrisDegnen is right about Control+Shift K, or Cmd+Shift K. But those key combinations or clicking this little triangle under function

will bring neat template syntax list right under function name in Mathematica 9:

I see. the reason it wasn't working for me is that I was hitting F1 after the openning bracket =) (which is how I did it in matlab). That'e exactly what I was looking for. –  Malabarba Dec 3 '12 at 13:20
Wait, when was this version 9 released? I bought my student license barely two weeks ago and I was only offered version 8. –  Malabarba Dec 3 '12 at 13:30
@BruceConnor Very recently - November 28, 2012 –  Vitaliy Kaurov Dec 3 '12 at 13:35
@BruceConnor -- If you just got your license it should allow you to upgrade to V9 –  Jagra Dec 3 '12 at 16:33
@Jagra I'm contacting customer service, but the website is asking for a £50 purchase. –  Malabarba Dec 3 '12 at 18:48

You may also use Ctrl+Shift+K, or +Shift+K to insert a template with the basic syntax already filled in with named placeholders.
