Thank you for your feedback.
אבג <space> <F!2>abc<space><F12> דהו
I get
אבג [ abc]דהו
Yes, that is what I would expect from the current implementation ( only
the space should be eliminated. Will check that.
when I move back (to the space) with the cursor the extra space is
eliminated (I've attached a screenshot to show how it looks on screen).
If I do the same thing in Lyx 1.4 (I guess it's the same as lyx1.5
without the patches) it results in
אבג [abc] דהו
In LyX 1.5 RC1 you will also get this, but internally (and later when
exporting to Latex!) you get the upper behavior.
But you have a point here. Maybe one can do something about it when
inserting character? Don't know yet.
