Hi I have to enter employee timecards and I have an excel file where I enter the start time, beginning of lunch, end of lunch and end time and it calculates hours worked for me. This is awesome and saves me time however, I have to enter the time in the HH:MM format, and having to enter the colon really slows me down. There's no colon on the 10-key pad! Is there anyway to use say a period instead?
