LCD Screen Editor: Selecting Insert or Overtype Mode

The LCD Screen Editor is always in one of two modes: Insert or Overtype.

In Insert mode, text that is typed or pasted from the clipboard is inserted. That is, any text following the insertion point is shifted to allow for the new text. Similarly, when text is removed—whether because a selection is deleted or cut to the clipboard—it is deleted, so that any text to the right of the removed text is shifted to fill the gap left by the removed text.

In Overtype mode, text that is typed or pasted from the clipboard overwrites text in the screen pane. The text does not shift. Similarly, when a text block is removed, that block is erased, but no text shifts. This does not apply to using the DELETE and BACKSPACE keys to delete a single character. The text to the right of the insertion point will shift accordingly.

The current mode is shown in two ways. First, on the status bar, an indicator will display INS for Insert mode and OVR for Overtype mode. Second, the insertion point in the screen pane will be a blinking vertical line in Insert mode and a blinking solid block in Overtype mode.

To switch between these two modes, press the INSERT key. The LCD Screen Editor starts up in Overtype mode.
