wdired-use-dired-vertical-movement

wdired-use-dired-vertical-movement is a variable defined in `wdired.el'.
Its value is

nil

Documentation:
If t, the "up" and "down" movement works as in Dired mode.
That is, always move the point to the beginning of the filename at line.

If `sometimes', only move to the beginning of filename if the point is
before it, and `track-eol' is non-nil. This behavior is very handy
when editing several filenames.

If nil, "up" and "down" movement is done as in any other buffer.

You can customize this variable.
