Just a quick follow-up. I used the code line below to trap the CTL-SHIFT-S combo and, somehow, everything seems to be working fine now. I don't understand what's different. Perhaps the moon changed its phases :-)
As a side point, I also tried setting the method up as an Action, although it doesn't look like CTL-SHIFT-S is one of the shortcut keystrokes available (...not that there aren't plenty of others from which to choose). Anyway, my thanks -- as always. It's great having a group like this available. I've never actually spoken face to face with someone who knows Delphi. All my communication about the topic has been via e-mail and newsgroups.
