Encapsulate multiple edits in a single Undo transaction?

[Ivan N. Zlatev]

How can I encapsulate multiple edits (e.g _insert_text) in one undo transaction? Something like

Code: [Select]

undo_transaction_open
_insert_text
_insert_text
undo_transaction_close
so that now I can undo everything betwwn open and close at once.

Hope I'm right - this should do what you want:

Code: [Select]

   // start a new undo 'level'
   _undo('S');

   // ... transaction

   if ( doUndo )  // undo the transaction
      _undo();
Used this a while ago but unfortunately I've deleted the macro.
