选择模式

标准选择

这是文本文档默认的选择模式。使用键盘，可以通过「Shift+导航键」(方向键、Home、End、向上翻页、向下翻页) 选择。使用鼠标，点击选择范围开始的地方，按住鼠标左键并移动到选择范围结束的地方。释放鼠标按钮可结束选择。

Extending selection

Use the mouse, arrow keys or the Home and End keys to extend or crop the current selection. Clicking anywhere in the text selects the region between the current cursor position and the click position.

Hold the Shift key to temporarily activate the Extending selection mode.

Adding selection (Shift+F8)

Use this mode to select multiple ranges of text. Each new selection using the mouse or keyboard is added as a new selection.

Hold the Ctrl key to temporarily activate the Adding selection mode.

Block selection (+Shift+F8)

Use this mode to select a non-contiguous block of text.

Hold the Alt key to temporarily activate the Block selection mode.
