Trim current view only?

Hi folks

When I use trim or extend commands and have to zoom or pan to select additional objects the command drops selection in previous view and only edits items in current view when executed.

Is there a system variable I can use to change this little time waster?

Are the objects selected by picking them individually, or with a crossing window? If you zoom or pan objects completely off the screen before completing the selection window, the objects that aren't visible won't be included.

Thanks for reply and sorry for not responding sooner. Can I change a system variable to enable change outside the current view.
