Hi Mirko,
 Unfortunately shortcuts are tricky. I’m not sure there is a definite solution to this. The reason is that on some keyboards # is a normal key, so cltr+# make sense, while on other keyboards is a composed keycode made, e.g. by shift+3. Then there is an ambiguity when typing ctrl+shift+3: is has to be interpreded literally (as the composition of two modifiers and the key 3) or as the composition of ctrl+(shift+3)?

This applies to other key combitations also.

As for me I always use the mouse to click the numbering equation command in the focus bar, is relatively fast and anyway I have to put the label if I want to use the number, so this will require even more typing.

But you can redefine the key-combination in your .TeXmacs file, of course.

HTH,
Best
Max
