Which version of TeXmacs? Of maxima?

If you have maxima-5.9.2, a sufficiently new TeXmacs, and you are in the 
math input mode, and
Preferences -> Keyboard -> Automatically close brackets
is on, then the following must work:

<Shift>-<F5> I x <space> d <tab> <tab> <space> x <enter>

You can check what you have really entered by Document -> View -> Edit 
source tree
You will see
<big|.>
(in blue) at the end of your integral.

If you use the toolbar to enter the integral sign, then this closing is 
not inserted automatically. You have to do it yourself:
\ b i g <tab> . <enter>
Here . means . (the dot character you have on your keyboard).
