The editor has two text-input modes:
Insertion mode: As you type on the keyboard, text is entered
at the insertion point and any text to the right of the insertion point is
shifted along. A visual indication of insertion mode is that the cursor is
a flashing line.
Overstrike mode: As you type on the keyboard, text at the
insertion point is replaced with your typing. A visual indication
of insertion mode is that the cursor is a flashing block.
Insert and overstrike modes are common to all editors: if one editor
is in insert mode, all editors are in insert mode. To configure
the cursor appearance, choose Tools > Options.
To toggle between insertion and overstrike mode:
When overstrike mode is enabled, the mode indicator changes from INS to
OVR and the cursor will change to the overstrike cursor.
To add or insert text:
- Move the insertion point to the place text is to be inserted.
- Enter the text using the keyboard.
To overwrite characters in an existing line, press the Insert key to
place the editor into overstrike mode.
