1. 修改 NoteEditViewModel

   fun playContent() {
       val content = _uiState.value.content.text
       if (content.isNotBlank()) {
           ttsHelper.speak(content)
       }
   }
   fun selectAllContent() {
       _uiState.update {
           it.copy(
               content = it.content.copy(
                   selection = TextRange(0, it.content.text.length)
               )
           )
       }
   }
   fun copyContent() {
       val selectedText = _uiState.value.content.selection
       if (!selectedText.collapsed) {
           val textToCopy = _uiState.value.content.text.substring(selectedText.start, selectedText.end)
           val clipboard = application.getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
           val clip = ClipData.newPlainText("note_content", textToCopy)
           clipboard.setPrimaryClip(clip)
       }
   }
   fun pasteContent() {
       val clipboard = application.getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
       val pasteData = clipboard.primaryClip?.getItemAt(0)?.text?.toString() ?: ""
       if (pasteData.isNotBlank()) {
           val currentContent = _uiState.value.content
           val newText = currentContent.text.replaceRange(
               currentContent.selection.start,
               currentContent.selection.end,
               pasteData
           )
           val newCursorPosition = currentContent.selection.start + pasteData.length
           _uiState.update {
               it.copy(
                   content = it.content.copy(
                       text = newText,
                       selection = TextRange(newCursorPosition)
                   )
               )
           }
       }
   }
   fun moveContentCursorToTop() {
       _uiState.update {
           it.copy(
               content = it.content.copy(selection = TextRange(0))
           )
       }
   }
   fun moveContentCursorToBottom() {
       _uiState.update {
           it.copy(
               content = it.content.copy(selection = TextRange(it.content.text.length))
           )
       }
   }
   

2. 修改 NoteEditScreen

   private fun NoteEditScreenContent(
       modifier: Modifier = Modifier,
       uiState: NoteEditUiState,
       onTitleChange: (androidx.compose.ui.text.input.TextFieldValue) -> Unit,
       onContentChange: (androidx.compose.ui.text.input.TextFieldValue) -> Unit,
       onSaveNote: () -> Unit,
       onPlayTitle: () -> Unit,
       onPlayContent: () -> Unit,
       onSelectAll: () -> Unit,
       onCopy: () -> Unit,
       onPaste: () -> Unit,
       onMoveToTop: () -> Unit,
       onMoveToBottom: () -> Unit,
       onNavigateBack: () -> Unit
   ) {
   

3. 修改 NoteEditScreen

   ) { innerPadding ->
       if (uiState.isLoading) {
           CircularProgressIndicator()
       } else {
           Column(
               modifier = Modifier
                   .padding(innerPadding)
                   .fillMaxSize()
           ) {
               TextField(
                   value = uiState.title,
                   onValueChange = onTitleChange,
                   label = { Text("標題") },
                   modifier = Modifier.fillMaxWidth()
               )
               TextField(
                   value = uiState.content,
                   onValueChange = onContentChange,
                   label = { Text("內容") },
                   modifier = Modifier
                       .fillMaxWidth()
                       .weight(1f)
               )
               // Function Panel
               LazyRow(
                   modifier = Modifier.fillMaxWidth(),
                   horizontalArrangement = Arrangement.spacedBy(8.dp)
               ) {
                   item { IconButton(onClick = onMoveToTop) { Icon(Icons.Default.ArrowUpward, contentDescription = "移至頂端") } }
                   item { IconButton(onClick = onMoveToBottom) { Icon(Icons.Default.ArrowDownward, contentDescription = "移至底端") } }
                   item { IconButton(onClick = onSelectAll) { Icon(Icons.Default.SelectAll, contentDescription = "全選") } }
                   item { IconButton(onClick = onCopy) { Icon(Icons.Default.ContentCopy, contentDescription = "複製") } }
                   item { IconButton(onClick = onPaste) { Icon(Icons.Default.ContentPaste, contentDescription = "貼上") } }
               }
           }
       }
   }
   

4. 修改 NoteEditScreen

   @Composable
   private fun NoteEditScreenPreview() {
       AndroidTemplateTheme {
           NoteEditScreenContent(
               uiState = NoteEditUiState(isLoading = false),
               onTitleChange = {},
               onContentChange = {},
               onSaveNote = {},
               onPlayTitle = {},
               onPlayContent = {},
               onSelectAll = {},
               onCopy = {},
               onPaste = {},
               onMoveToTop = {},
               onMoveToBottom = {},
               onNavigateBack = {}
           )
       }
   }
