插入模式

Displays the current insert mode. You can toggle between INSRT = insert and OVER = overwrite.

Click in the field to toggle the modes (except in the Collabora Office Basic IDE, where only the Insert mode is active). If the cursor is positioned in a text document, you may also use the Insert key (if available on your keyboard) to toggle the modes.

INSERT	在插入模式中，新字元會插入游標所在位置；接著的文字則會向右移動。游標則顯示如垂直划線。
OVER	在覆寫模式中，新字元會覆寫現有字元。游標則顯示如區塊。
