locate /character string/to search for a certain character string. The command is explained in detail in section LOCATE.
From bottom to top you may search with the command RLOCATE (`reverse locate').
With the commands NLOCATE (`negative locate') and RNLOCATE (`reverse negative locate') or NRLOCATE (`negative reverse locate') you receive the nearest line that does not contain the specified character string.
As the minimal abbreviation for LOCATE is only L and as exaEdit memorizes the character string that was searched for last, the repetitive search for the same character string is quite simple: you only have to give the command L. Please keep in mind, that you may define one of the F keys with the LOCATE command (compare section exaEdit Functions), which allows you to find different character strings with once pressing a key.
The stored character string that has been searched for remains the same for any form of the LOCATE command. So, you only need to give the command RLOCATE to search backwardly for the same character string that you were searching for forwardly in advance.
