the SVr4 curses library used the \fBget_mouse\fP capability to tell the
terminal which mouse button events it should send,
passing the mouse-button bit-mask to the terminal.
-Also, it could ask the terminal where the mouse was using the \fBreq_mouse_pos\fP capability.

Those features required a terminal which had been modified to work with curses.
They were not part of the X Consortium's xterm.

Mouse events under xterm will not be detected correctly in a window with
its keypad bit off, since they are interpreted as a variety of function key.

Other values for \fBkmous\fR are permitted,
but under the same assumption,

Because there are no standard terminal responses that would serve to identify
terminals which support the xterm mouse protocol, \fBncurses\fR assumes that
-if your $TERM environment variable contains "xterm",
-or \fBkmous\fR is defined in
-the terminal description, then the terminal may send mouse events.
+if \fBkmous\fR is defined in the terminal description,
+or if the terminal description's primary name or aliases
+contain the string \*(``xterm\*('',
+then the terminal may send mouse events.
+The \fBkmous\fP capability is checked first,
+allowing the use of newer xterm mouse protocols
+such as xterm's private mode 1006.
