+Clipboard:
+- toClipboard: Store oldText to a named clipboard before the operation
+- fromClipboard: Use clipboard content as newText (ignores provided newText)
+- Clipboards persist across patch calls
+- Always use clipboards when moving/copying code (within or across files), even when the moved/copied code will also have edits.
+ This prevents transcription errors and distinguishes intentional changes from unintentional changes.
+
+Indentation adjustment:
+- reindent applies to whatever text is being inserted
+- First strips the specified prefix from each line, then adds the new prefix
+- Useful when moving code from one indentation to another
+
+Recipes:
+- cut: replace with empty newText and toClipboard
+- copy: replace with toClipboard and fromClipboard using the same clipboard name
+- paste: replace with fromClipboard
+- in-place indentation change: same as copy, but add indentation adjustment
