Arguments: None
Key sequence:
Ctrl+X O

Arguments: None
Key sequence: None
Changes the current window to be the previous window visited, and the current buffer to be the buffer that is displayed in that window.
Arguments: None
Key sequence:
Ctrl+X 0
Deletes the current window. The previous window becomes the current window.
Arguments: None
Key sequence:
Ctrl+X 1
Deletes the next window in the window ring.

A prefix argument causes the appropriately numbered window, from the top of the window ring, to be scrolled.
Arguments: None
Key sequence: None
The next window in the window ring is scrolled up.
A prefix argument causes the appropriately numbered window, from the top of the window ring, to be scrolled.
Arguments: None
Key sequence: None
Controls the size of the scroller in editor-based tools, and how the Editor tool's mode line represents the extent of the displayed part of the buffer.
Toggle Count Newlines
switches between counting newlines and counting characters in the current buffer. The counting determines what is displayed in the Editor tool's mode line, and how the size of the scroller is computed.
When counting newlines, the mode line shows line numbers and the total number of lines:
StartLine
-
EndLine
[
TotalLine
]
When counting characters, the mode line shows percentages based on the characters displayed compared to the total number of characters in the buffer:
PercentStart
-
PercentEnd
%
The default behavior is counting newlines, except for very large buffers.
Arguments: None
Key sequence:
Ctrl+L
Moves the current line to the center of the current window, and then re-displays all the text in all the windows.
A prefix argument of 0 causes the current line to become located at the top of the window. A positive prefix argument causes the current line to become located the appropriate number of lines from the top of the window. A negative prefix argument causes the current line to become located the appropriate number of lines from the bottom of the window.
