I am working with the accessibility system emacspeak to improve
eyes-free access to org-mode tables. Most of this can be done outside
the org-mode tree by advising existing functions but I've run into a
need for a new function. I need org-table-previous-row analogous to
org-table-next-row. Below is a patch to add this. The behaviour is
almost identical to org-table-next-row except that
org-table-previous-row in the first row of the table is a no-op.
Please consider adding this to the repository. Comments and
corrections welcome but please send them to me directly as well as the
list.
regards
Peter
