Movement:
left/right arrow move one character (where entering or exiting an inset,
such as going into/out of a subscript, counts as a "character" for movement
purposes);
ctrl-left/right jumps the adjacent "grouping", where "grouping" is the
subtree at the current node if we were to diagram the math inset as a tree;
home/end jumps to the start or end of the entire inset;
ctrl-home/end jumps to the start or end of the buffer (document).
Selection: shift+any navigation combination selects everything from the
current cursor position to where the unshifted key combination would take you.
As I wrote, this is not entirely possible.
I don't know if Guillaume's patch would fix this or not. Right now, there do
not seem to be any LyX functions (LFUNs) that relate to this notion of a
"grouping" or syntactic tree node.
My patch assigns the behaviour you describe for ctrl+arrows to word-*
movement lfuns.
Internally (meaning in the C++ code),
something like that seems to exist from what Jean-Marc wrote.
Jean-Marc suggested to skip bigger chunks delimited by their category
(reation, operator...). This would make sense for both ctrl+arrows and
ctrl+shift+arrows. This does not exist yet and we can give it a try once
Jean-Marc commits his patch that defines these categories, which I
encourage him to do.
