What is the correct form strategy to ease numerical data entry into a table that requires multiple records?

tblHourlySales tracks the sales per hour of our store. Each record has 4 fields:
pk
CalendarDate
Hour
Sales

At the end of the day I want to be able to enter sales using a 10 key pad to make entry quick i.e.


105
210
358
etc

So by typing a column of sales numbers I get,
1 7/26/2010 11:00am $105
2 7/26/2010 12:00pm $210
3 7/26/2010 1:00pm $358
etc
What's the best strategy to make this easy? I have come across several potential solutions, but want to get it right the first time.

Thanks!!!!
