# Overtype and insert commands

When the Update processor is first entered, it is in overtype
mode. This means any characters typed overwrite the characters on
the screen. Insert mode is used to insert new text just in front of
the text beginning at the cursor. When text is typed in the insert
mode, the entered text is opened and shown on the next line until
insert mode is exited or a cursor movement command is typed.

The letter **O** displays at the top right corner of
the screen when in overtype mode; the letter **i** displays when
in insert mode. As text is entered in either mode, the Update processor
word wraps the text as necessary.

| CTRL+R | Toggles between overtype and insert modes. |
