hello. apologies as this has probably been covered but a quick search didn't turn it up. i like to keep my hands on the keyboard whenever possible rather than point and click. the first thing i'd like to do using the keyboard is to jump to a precedent cell that's referenced by a formula in my selected cell. i understand i can trade precedents than click on arrows, etc. but how do i do that stuff using the keyboard? the second thing i'd like to do is to fill a formula all the way down a column w/ a keyboard combination, rather than double clicking on the lower right hand corner of the cell in qustion. thanks in advance!
