Text entered at the keyboard is inserted into the buffer. In
overwrite mode, which can be toggled by pressing
INSERT, one character is deleted from in front of the
caret position for every character that is inserted. The caret is drawn
as a horizontal line while overwrite mode is active. The status bar also
indicates if overwrite mode is active; see the section called “The Status Bar”
Inserting text while there is a selection will replace the selection with the inserted text.
When inserting text, the
ENTER keys might not behave entirely like you expect
because of various indentation features; see the section called “Tabbing and Indentation”
The simplest way to delete text is with the
DELETE keys. If nothing
is selected, they delete the character before or after the caret,
respectively. If a selection exists, both delete the selection.
