The editor uses the following vocabulary:
- editor
<-caret
Current position of the insertion-point, indicated using a
text_cursor
object. For proportional fonts, this is a triangle with a vertical
line-segment. For fixed fonts, this is a static block.
- editor
<-mark
Unvisible point that, together with the editor<-caret,
describes the REGION. Many operations work on a REGION of the entire
text (deleting, formatting, etc.).
- region All characters between the editor
<-caret
and the editor<-mark.
- argument Many interactive operations accept a numeric argument. The
numeric argument is set using one of the sequences
\C-u digit ...
M-<digit> ...
and reset after the completion of the next interactive command. The
interpretation is command dependent, but most commands interpret the
argument as do this command so many times.
