# Preference Sections
by Brent Welch

Here is a short summary of the preference sections and the features that they control. This summary names the corresponding Tcl module in (parentheses) so that you can dig into the code if you want to. This section is very terse because there are more lengthy explanations of all the settings in the online preference dialogs. This section provides an overview so you can find the preference section that applies to the feature you want to control.

Hacking Support
  Enable the debug log. A `Log` button appears; click on it to view the log contents. Insert `Exmh_Debug` calls in your Tcl code to log information. Define the directory for personal Tcl code. (main.tcl)
MH Tweaks
  Enable background message sending. Choose whether the names of deleted files will start with `,` (comma) or `#` (hash mark). Define the age of files to purge. (mh.tcl)
Simple Editor
  Adjust formatting parameters. Enable automatic signatures. (sedit.tcl)
Editor Support
  Define an external editor, spell program, and mhn command. (editor.tcl)

Scan Listing
  Set the number of lines in the table of contents (scan listing) here. Tweak message viewing: `Implied Direction`, `Next Guard`, `Auto Commit`, `Advance After Link`, `Show New Messages`, `Skip Marked`. Choose the scan format width. (ftoc.tcl)
MIME
  Adjust the MIME message display. Note that the font sizes chosen here don't affect non-MIME messages. (mime.tcl)
