How do you correct a partial in-correct entry?

i.e. put in bib #53 instead of #58 and want to make the correction before competitor crosses the finish line.

What program are you asking about? Backup, Stopwatch?

In Stopwatch (lite) you just overtype the mistaken bib number with the correct one and press RED "OK".

The new net running time for the input bib number will appear.
