Ok, here's what I've got.
In the screenshot, you'll see three things- a start time, end time and total time. So the goal is this-
A user puts in a current start time by hitting F1 at the start of shift. They tab across the end time to the "time field", then go across the row.
Then they enter their case number, then hit F1 again, and it will enter the current time in the start box on the next row, as well as putting that time in the end box in the row above...
And keep doing this down the whole form.
I hope this makes sense. If anyone can think of a better way to do this, I'm all ears. I need help with the code.
