It's been a while since I used my Windows machine, but I think I used to click the "F2" button to edit a Windows Excel cell. Would someone please tell me how to do that in Apple's version of Excel. Currently, I find myself having to click my mouse on the entry window at the top of the screen. Also, how do I anchor cells, for instance $A$15? In Windows, I could scroll through the F4 key, but cannot figure out how to do that on the iMac. Finally, is there a key I can push to highlight all the linked cells in an Excel formula. Again, I currently have to click on the formula bar at the top of the screen. Thank you!
