I overlooked pos-visible-in-window-p before, thanks for the reference.
Do you have any points of advice for avoiding side-effects when moving
the cursor around the buffer programmatically?
What I have so far:
- Wrap in save-excursion
- Bind to t:
- inhibit-point-motion-hooks
- cursor-sensor-inhibit
- inhibit-field-text-motion (for precision, might be superfluous)
- Bind to nil:
- goal-column (probably superfluous)
Thanks Eli, I appreciate the help and also the work you do for Emacs.
