Entering acct numbers or acct description in field

In the general ledger section, the drop down box has to be active to bring up the list of accounts. It does not have a search feature in the actual box.

I use account numbers to enter information and have a list posted on the side of my monitor for reference. This allows me not to use the drop down box and makes data entry faster.

Is there a way to implement this?

Not sure I understand this one. Can you post screenshot so I can see what screen you are talking about?
