Hello,

 

I migrated from LaTeX to TeXmaX some years ago, but I probably still use the latter rather incorrecly, having learned it by the "click and see what happens" method.

 

I have still not discovered how to reproduce the construct \mathop{\longrightarrow} _ {x \rightarow \infty} ^ {D \prime} which gives a much nicer appearance than does using \stackrel or the stack option by mouse in Texmacs.

 

Nor have I discovered how to obtain the character \hbar, essential for quantum physics! 

 

I would also like to find a way of getting the symbol sometimes used (in France at least) for the distribution which is a sum over integer n of Dirac distributions \delta (x-n) (peigne de Dirac). It looks like a comb : in Latex my best attempts have been \lfloor | \rightfloor or \lfloor \perp \rightfloor.

 

Thanks in advance for any help on these questions.

 

Best wishes for the coming year,

 

Richard Tweed
