emacs: Other Window
20.3 Using Other Windows
========================
‘C-x o’
Select another window (‘other-window’).
‘C-M-v’
Scroll the next window (‘scroll-other-window’).
‘mouse-1’
‘mouse-1’, in the text area of a window, selects the window and
moves point to the position clicked. Clicking in the mode line
selects the window without moving point in it.
With the keyboard, you can switch windows by typing ‘C-x o’
(‘other-window’). That is an ‘o’, for “other”, not a zero. When there
are more than two windows, this command moves through all the windows in
a cyclic order, generally top to bottom and left to right. After the
rightmost and bottommost window, it goes back to the one at the upper
left corner. A numeric argument means to move several steps in the
cyclic order of windows. A negative argument moves around the cycle in
the opposite order. When the minibuffer is active, the minibuffer is
the last window in the cycle; you can switch from the minibuffer window
to one of the other windows, and later switch back and finish supplying
the minibuffer argument that is requested. Minibuffer Edit.
The usual scrolling commands (Display) apply to the selected
window only, but there is one command to scroll the next window.
‘C-M-v’ (‘scroll-other-window’) scrolls the window that ‘C-x o’ would
select. It takes arguments, positive and negative, like ‘C-v’. (In the
minibuffer, ‘C-M-v’ scrolls the help window associated with the
minibuffer, if any, rather than the next window in the standard cyclic
order; Minibuffer Edit.)
If you set ‘mouse-autoselect-window’ to a non-‘nil’ value, moving the
mouse over a different window selects that window. This feature is off
by default.
