14 The Tool Bar

Emacs also provides a graphical tool bar. For a description of the tool bar, please see the section Tool Bars in The GNU Emacs Manual.

MH-E adds several icons to this tool bar; you can modify the MH-E aspects of the tool bar via the ‘mh-tool-bar’ customization group.


List of buttons to include in MH-Folder tool bar (default: a checklist too long to list here).


List of buttons to include in MH-Letter tool bar (default: a checklist too long to list here).


Function called by the tool bar search button (default: mh-search).

Icons for some of MH-E’s functions are added to the tool bar.

In either case, you can select which of these functions you’d like to see by customizing the options mh-tool-bar-folder-buttons and mh-tool-bar-letter-buttons. As you probably guessed, the former customizes the tool bar in MH-Folder mode and the latter in MH-Letter mode. Both of these options present you with a list of functions; check the functions whose icons you want to see and clear the check boxes for those you don’t.

The function associated with the searching icon can be set via the option mh-tool-bar-search-function. By default, this is set to mh-search. See Searching Through Messages. You can also choose ‘Other Function’ from the ‘Value Menu’ and enter a function of your own choosing.
