26.6 Mode Line Mouse Commands
You can use mouse clicks on window mode lines to select and manipulate
Some areas of the mode line, such as the buffer name and the major
mode name, have their own special mouse bindings. These areas are
highlighted when you hold the mouse over them, and information about
the special bindings will be displayed (see Tooltips).
You can also click on areas of the mode line that do not have
special mouse bindings of their own. This has the following effects:
- Mouse-1 on a mode line selects the window it belongs to. By
dragging Mouse-1 on the mode line, you can move it, thus
changing the height of the windows above and below.
- Mouse-2 on a mode line expands that window to fill its frame.
- Mouse-3 on a mode line deletes the window it belongs to. If the
frame has only one window, it buries the current buffer instead, and
switches to another buffer.
- C-Mouse-2 on a mode line splits the window above
horizontally, above the place in the mode line where you click.
C-Mouse-2 on a scroll bar splits the corresponding window
vertically. See Split Window.
