See the attached .tm file. Note that labels for equation arrays 
(Insert->Mathematics->Several equations) need to be placed after the eq. 
number, while for a regular equation (Insert->Mathematics->Displayed formula) 
need to be placed somewhere before the eq. number (I usually place the label 
to the beginning of the line, but I guess you can alternatively place it to 
the end of the equation but prior to the eq. number).

See the enclosed .tm file for regular sequential nubering. If you want to do 
something more fancy, like (1.a), (1.b) instead of (1), (2), this probably 
can be done by re-defining the numbering macros but I never tried.

I usually put those to the preamble, see the enclosed .tm file where the 
preamble contains my macros for /bra, /ket, /braket, /ketbra, /braket-element.

Cheers,
Peter.

P.S.: 
To create the preamble in a new document: Document->Part->Create preamble
To switch between showing an existing preamble & the main document: 
Document->Part->Show preamble or Show all parts


P.P.S.: I wish someone included the /bra, /ket, /braket, /ketbra, 
/braket-element to the standardly supported set of commands in TeXmacs 
(perhaps using some implementation superior to mine). Developers, anyone? :-)
