OK, thanks for your patience! :) I think turning off the "extended" Home and End keys fixed it. I say "I think" it fixed it because it seems I always have to press End twice to get it to go to LineEnd (it ignores the first press). I can live with that, so thanks!
I do think the program is acting differently than it used to in this area. I have installed multiple new versions over the last few years and this is the first time I have had any trouble with regard to key presses. But thanks for the way to get around it. :) -- <https://forum.pspad.com/read.php?2,78310,78316> PSPad freeware editor https://www.pspad.com
