26.17 Tool Bars
The tool bar is a line (or lines) of icons at the top of the
Emacs window, just below the menu bar. You can click on these icons
with the mouse to do various jobs.
The global tool bar contains general commands. Some major modes
define their own tool bars to replace it. A few “special” modes
that are not designed for ordinary editing remove some items from the
global tool bar.
Tool bars work only on a graphical display. The tool bar uses colored
XPM icons if Emacs was built with XPM support. Otherwise, the tool
bar uses monochrome icons (PBM or XBM format).
You can turn display of tool bars on or off with M-x
tool-bar-mode or by customizing the option tool-bar-mode
.
