QuickBooks 2006 makes it easy for you to perform calculations and editing. If the selection cursor is on an amount field, you can use these symbol keys to make calculations:

Press What Happens
+ Adds the number you just typed to the next number you type
- Subtracts the next number you type from the number you just typed
* Multiplies the number you just typed by the next number you type
/ Divides the number you just typed by the next number you type

If the selection cursor is on a date field, you can use these tricks to edit the date:

Press What Happens
+ Adds one day to the date shown
t Replaces the date shown with today's date
- Subtracts one day from the date shown
y Changes the date to the first day in the year
r Changes to date to the last day in the year
m Changes the date to the first day in the month
h Changes the date to the last day in the month
