Display Commands
The Ctrl-L command causes Epsilon to center point
in the window. If you give a numeric argument to Ctrl-L, Epsilon
makes the current line appear on that line of the window. For
instance, give a numeric argument of zero to make the current line
appear on the topmost line of the window. (The line-to-top
command is another way to do this.) If you give a numeric argument
greater than the number of lines the window occupies, Epsilon will
position the current line at the bottom of the window. (The
line-to-bottom command is another way to do this.) When
repeated, the Ctrl-L command also completely refreshes the screen.
If some other program has written text on the screen, or something
has happened to garble the screen, use this command to refresh it.
The Alt-<Comma> and Alt-<Period> commands move point to the
first and last positions displayed on the window, respectively.
The Ctrl-Z and Alt-Z commands scroll the text in the window up or
down, respectively, by one line. These scrolling commands will move
point as necessary so that point remains visible in the window.
The Ctrl-V and Alt-V commands scroll the text of the window up or down,
respectively, by several lines fewer than the size of the window.
These commands move point to the center line of the window.
You can control the exact amount of overlap between the original
window of text and the new window with the window-overlap
variable. A positive value for this variable means to use
that number of screen lines of overlap between one window of text
and the next (or previous). A negative value for
window-overlap represents a percentage of overlap, instead of
the number of screen lines. For example, the default value for
window-overlap of 2 means to use 2 lines of overlap. A value
of -25 for window-overlap means to overlap by 25%.
You can change how Epsilon pages through a file by
setting the variable paging-centers-window. Epsilon normally
positions the cursor on the center line of the window as you move
from page to page. Set this variable to zero if you want Epsilon to
try to keep the cursor on the same screen line as it pages.
The goto-line command on
Ctrl-X G prompts for a line number and then goes to the beginning of
that line in the current buffer. If you prefix a numeric argument,
Epsilon will use that as the line number. Use the format 10:20
to include a column specification; that one goes to line 10, column
number 20. Or use a percent character to indicate a buffer
percentage: 25% goes to a line 25% of the way through the
buffer.
The Ctrl-X L command shows the number
of lines in the buffer and the number of the line containing point.
It also shows the number of bytes the file would occupy if written to
disk. This can differ from the size of the buffer, because the
latter counts each line separator as a single character. Such
characters require two bytes when written to disk in the format used
in Windows, DOS, and OS/2, however. See Line Translation
for information on how Epsilon translates line separator characters.
The Ctrl-X = command displays in the echo area information
pertaining to point. It shows the size of the buffer, the
character position in the buffer corresponding to point, that
character's column, and the value of that character in decimal,
hex, and "normal" character representation.
