The following commands act on entire Prolog predicate definitions as a single unit:
Move forward from point to the next predicate definition in the
current buffer (sweeprolog-forward-predicate).
Move backward from point to the previous predicate definition
(sweeprolog-backward-predicate).
Select the current predicate as the active region, put point at the
its beginning, and the mark at the end
(sweeprolog-mark-predicate).
In Sweep Prolog mode, the commands M-n
(sweeprolog-forward-predicate) and M-p
(sweeprolog-backward-predicate) are available for quickly
jumping to the first line of the next or previous predicate definition
in the current buffer.
The command M-h (sweeprolog-mark-predicate) marks the
entire predicate definition at point, along with its ‘PlDoc’
comments if there are any. As an example, you can use this command to
move an entire predicate definition typing M-h C-w and then
yanking it elsewhere with C-y.
