   Voila! Proof!   
      
   This was posted to the Firefox newsgroup just moments ago, but it also   
   belongs to the Windows newsgroup because the debug below is on Windows.   
      
   It proves the "problem" which proves the PSA correct.   
   But even better, it explains the "solution" which is what is needed.   
      
   Note the "format" is a numeric identifier that Windows uses internally to   
   label a clipboard format.   
    Format ID 1      = CF_TEXT   
    Format ID 7      = CF_OEMTEXT   
    Format ID 13     = CF_UNICODETEXT   
    Format ID 16     = CF_LOCALE   
   These are built in Windows formats.   
   They exist on every Windows system.   
      
   Yet the important ones in this test are:   
    Format ID 49426  = HTML Format   
    Format ID 49661  = Chromium internal source RFH token   
    Format ID 49683  = Chromium internal source URL   
      
   For each of those, Chromium told Windows (taking one as an example):   
     "I want to register a clipboard format named HTML Format"   
      and Windows assigned it ID 49426.   
      
   Why are the numbers so big?   
   Because Windows built-in formats use small numbers:   
     1, 7, 13, 16, etc.   
   While application-registered formats use large numbers:   
    49426, 49661, 49683.   
      
   These indicate that Chromium placed multiple formats on the clipboard   
    HTML Format   
    Chromium internal source RFH token   
    Chromium internal source URL   
      
   But when your Notepad++ macro rewrote the clipboard, all of those formats   
   disappeared.   
    A. This is why Ctrl+A started working again.   
    B. The shortcuts.xml CTRL+B macro removed the HTML Fragment land mine   
      
   Voila!   
   I love one-step automation!

   Hi Lawrence,   
      
   I, for one, greatly admire and appreciate what Lawrence has done for the   
   team, especially as Apple, Linux and Firefox users are on this thread.   
      
   I ran NirSoft InsideClipboard on Windows today and saw the same pattern   
   that Lawrence showed on Linux. Chromium placed CF_TEXT, CF_UNICODETEXT,   
   CF_LOCALE, HTML Format, and two Chromium internal formats on the   
   clipboard. That matches his Linux results one for one, just expressed in   
   Windows clipboard terminology instead of MIME types

   What Lawrence didn't do, since he wasn't cleaning text and I am, is run it   
   through the Notepad++ macro, which puts things back on the clipboard.   
      
   This is the NirSoft InsideClipboard result after running Control+B   
   (which adds a space, deletes it, cleans the text, & repopulates the   
   clipboard with the cleaned text and wipes it off of N++ in 1 step).

   I have no idea, just yet, what that means in detail, but it seems to show   
   a. Chromium always puts plain text formats on the clipboard.   
   b. Chromium always puts HTML Format on the clipboard.   
   c. Chromium always puts its internal metadata formats on the clipboard.   
      CF_TEXT   
      CF_OEMTEXT   
      CF_UNICODETEXT   
      CF_LOCALE   
      HTML Format   
      Chromium internal source RFH token   
      Chromium internal source URL   
      
   This appears to match Lawrence's Linux results one for one.   
   Hence, I believe it confirms the Chromium part of the PSA.   
      
   While the Notepad++ macro is really part of a separate Windows thread, we   
   note here that after the CTRL+B macro ran, the clipboard contained only:   
      CF_TEXT   
      CF_OEMTEXT   
      CF_UNICODETEXT   
      CF_LOCALE   
      
   The control+b macro stripped out all non text formats, including:   
      HTML Format
