Just bought my first mac and I'm having some problems getting used to excel 2011. I'm an MBA student and for the most part I live inside of Excel but I'm not understanding some of the basic operations in the mac version. My most immediate issue: On the mac version of excel when I type =su in a cell I get a drop down with the list of possible functions just like on the PC, but when I'm nested in a formula for example I've typed "=sumproduct(su" I don't get the dropdown again like I would with the PC. I have to literally finished typing the whole function before I see the param help box. Am I doing something wrong there? Also can you tab functions inline? What I mean is on the PC version if I type "=sump" I can just hit tab and automatically it pops up =sumproduct() and places the cursor inbetween the (). On my mac I have to press the down arrow and select sumproduct even if its the only one of the list. Can I fix this? Thanks to all.
