Windows 7 – Use function keys for pasting specific text

I want to assign some text to F keys on Windows 7.   

For example, I want to press F5 to paste “000”, or press F6 to paste “.00 US Dollars”.

It would be appreciated if anyone can help me (a piece of software or code).

Solution:

The easiest way is to use Autohotkey.

You can then edit the default script to add:

F5::Send 000F6::Send .00 US Dollars
