   Thanks for trying to help out, Andy, as I respect your knowledge and that   
   of Paul, Carlos, and others, as I will always be open when I say I never   
   really understood this stuff but I need to fix it with my Notepad++ macro.   
      
   One of the first things I tried was Control+Shift+V and the Notepad++ hex   
   editor, but neither seemed to help so I gave up on both of them long ago.   
      
   Notepad++'s "Paste Simple Text" command only works if the clipboard   
   actually contains a plain-text flavor that Notepad++ recognizes as usable.   
      
   Chromium does put plain text on the clipboard but there's a catch.   
   Chromium puts the HTML flavor first & marks it as the "preferred" format.   
      
   Even when we use Paste Simple Text, Notepad++ still has to ask Windows for   
   the available formats. If Windows reports the HTML flavor as the "best   
   text-like format," Notepad++ may still pick it.   
      
   Given that inconsistency, it seems...   
    a. Ctrl+V always triggers HTML fragment mode   
    b. Ctrl+Shift+V sometimes still triggers HTML fragment mode   
   The only guaranteed way to break the mode is to modify the buffer (i.e.,   
   insert/delete a line).   
      
   My issue is I can't fix it in my Notepad++ macro until I understand it.   
   And to understand it, I'd like to *see* it. But it's invisible!   
      
   Oddly, I don't see this problem with Mozilla browsers.   
   Just Chromium-based browsers.   
      
   Huh?   
      
   Interestingly, both Chromium and Firefox can place multiple formats on the   
   clipboard (plain text, HTML, images, etc.). That part is normal and very   
   old Windows behavior as Carlos astutely already noted in a prior post.   
      
   Chromium browsers (Edge, Chrome, Brave, Vivaldi, Electron apps) add extra   
   metadata to the HTML clipboard flavor, e.g., StartHTML, EndHTML,   
   StartFragment, EndFragment.   
      
   Notepad++ interprets this as a fragment boundary and enters "HTML fragment   
   mode." That's what breaks Ctrl+A and Ctrl+X.   
       
      
   Firefox does not add those fragment markers in the same way. It typically   
   places plain text and a simpler HTML representation without the   
   Chromium-style fragment metadata.   
       
      
   Go figure. Did I mention I never understood all this character stuff?
