Customization
As with most X applications, xterm can be customized via global X resources file (e.g. /usr/lib/X11/app-defaults/XTerm), per-user resource files (e.g. ~/XTerm; ~/.Xresources) or command-line arguments. Most of the command-line options correspond to resource settings, as noted in the manual page.
While the name of the program is xterm, the X resource class is XTerm. The uxterm script overrides this, using the UXTerm resource class.
xterm normally does not have a menu bar. To access xterm's three menus, users must hold the Control key and press the left, middle, or right mouse button. Support for a "toolbar" can be compiled-in, which invokes the same menus.
