Tabbing order of fields

[AC]

Is there a way to rearrange the order of tabbing between fields in a
ledger?  I'm using one of the mutual fund ledgers and after I tab to
exit the description field it skips the next columns "shares" and
"price" and goes straight to either the "buy" or "sell" field (depending
on the auto-fill).  I'd like to go to "shaes" first  then price (so I
can erase it) instead of having to go backwards then forwards again.
