This section describes settings and additional configuration panels offered by the UI client.


JEB ships with a default (clear) theme and a Dark theme.

Toggle from default to Dark, and vice-versa, via the Edit, Theme command (or the Ctrl+Shift+Alt+T keyboard shortcut).

Styles and Fonts

The Edit menu (or the Application menu on Mac) allows users to customize the styles of interactive item as well as the code font used by most JEB views.

Make sure to select a fixed font. JEB tries its best to select the most appropriate font on your system; if that fails, and you wish to select a font manually, we recommend Consolas on Windows, Menlo/Monaco on Mac, or DejaVu Sans Mono on Linux.

Unicode: JEB supports Unicode. While the aforementioned fonts have good support for a variery of common non-ASCII planes (CJK, Russian, etc.), you might need to use a different fonts to properly examine strings written in exotic locales.

Keyboard Shortcuts

Most JEB handlers can be triggered by keyboard shortcuts. The default shortcuts are visible when visualizing menu items.

To customize keyboard shortcuts:

Refer to the jeb-shortcuts.cfg.TEMPLATE file in your bin/ folder for details:

# JEB Custom Keyboard Shortcuts

# 1) Rename or copy this file to jeb-shortcuts.cfg
# 2) Uncomment and add your own keyboard shortcuts for the actions for which you'd like to override the default shortcuts

# Example: by default, Jump is mapped to the 'G' key; the following line (minus the # character) can be used to remap the action to CTRL+J:
