You can enter all your data with nothing more than the Tab key and some typing, but here are a few keyboard tricks that will make the job easier:
To insert the current date, press Ctrl+; (semicolon). To insert the current time, press Ctrl+: (colon).
If you have defined a default value for a field (in Table Design view), you can insert it by pressing Ctrl+Alt+Spacebar.
To repeat the value from the same field in the previous record, press Ctrl+' (apostrophe).
