[Fluxus] couple of editor fixes

[Ted]

I may have found an idear which can improve the editor in three ways but
same concept.
I was thinking about jumping to the next  (and previous) word
(like Ctrl + -> and Ctrl + <-) Classic!
and make a jump to the next (and previous) opening bracket
(like Ctrl + < and Ctrl + Shift + <)
and make a jump to the next (and previous) closing bracket or the
closing bracket associated to the opening on which the cursor is. (you
follow me? ;-)
(like Ctrl + > and Ctrl + Shift + >)

I think you mention something like this with the selection ability but a
quick navigation in scheme file by bracket should be interesting
(especially in big files).

What do you think about this?

Yours,
Ted
