Inserting and Overwriting Text
You can enter text in insert mode or overwrite mode. Insert mode is
the default. The word Ins is displayed at the bottom right corner of
the display.
To insert text, position the cursor at the point where the new text is
to start and begin typing. The existing text moves to the right as new
text is inserted.
To switch to overwrite mode, press the Ins key. The word Ins changes
to Ovr and the cursor changes to a block cursor. In overwrite mode,
all the text to the right of the cursor is overwritten with new text.
To switch back to insert mode, press the Ins key again.
Deleting Text
Text can be deleted one character at a time or one line at a time. To
delete the character at the cursor, press the Del key. The character
is removed from the screen, and the text from the right is shifted
left one character. To delete to the left of the cursor, press the BkSp
(backspace) key.
To delete a line, position the cursor anywhere on the line to be
removed and press the F8 key. The line is deleted and the lines below
it move up. The line just deleted is placed in a buffer until another
line is deleted and takes its place. The last line deleted can be pasted
back into the document using the undelete line command, F3.
