/** The cursor.
|
|
Later this variable has to be removed. There should be no internal
|
|
cursor in a text (and thus not in a buffer). By keeping this it is
|
|
(I think) impossible to have several views with the same buffer, but
|
|
the cursor placed at different places.
|
|
[later]
|
|
Since the LyXText now has been moved from Buffer to BufferView
|
|
it should not be absolutely needed to move the cursor...
|
|
[even later]
|
|
Nevertheless, it should still be moved, in order to keep classes
|
|
and interdependencies small.
