Hi Mario,

...
Consider
\frac{1}{2} + \left(1+1\right) = 2.5
^ ^ ^ ^ ^
A B C D E
Wherever I am, if I hit ctrl+right I am driven to E.
What I would like is that if I am in A I land in B and if I am in C I go
to D
...
What I have not been able to understand is which function I should bind
to ctrl+right so that this combination drives me from A to B or from C
to D instead of from everywhere to E
I agree ctrl+arrows could do better. The attached patch implements your
suggestion.
Pro: I find this behaviour more useful. It could be made better by
skipping strings of characters that constitute "words", but I am not
sure how to define this notion properly in mathed. (Jean-Marc speaks of
using the rel/bin/op categories to find a criterion, let's think about it.)
Con: it is a bit unintuitive that ctrl+arrow behaves differently from
ctrl+shift+arrows. But I believe that the current behaviour of
ctrl+shift+arrows is fine and should be kept.
Incidentally, I also do not like very much the fact that if in A then
shift+right selects all the A-B portion of the formula: in my view, this
should be the behavior of
ctrl+shift+right, whereas shift+right should select only the very next
character (that is, the numerator if I am in A).
Selections in LyX correspond to meaningful objects, not portions of
LaTeX code such as \frac{1} in your example. So what you propose for
shift+right does not make sense to LyX.
As for ctrl+shift+arrows, I find them useful to select entire insets
quickly.
