Quickfix for introducing a local variable from selection / expression under cursor

Just having evaluated Qt Creator 2.0.0 I was happy to find my suggestions for [Ctrl][Alt][Up] (create copy of current code line above current line) and [Ctrl][Alt][Down] (copy current line below) working! :-D

Being able to use them now made me realize, that I miss these closely related ones, too: [Alt][Up] and [Alt][Down].
They should move the selected line(s) up and down which is quite useful in combination with the above ones.

Another nice Eclipse shortcut is: [Alt][Shift][L]. In Eclipse this shortcut generates a local variable for the expression before the cursor or the selected expression and inserts that variable. To example it, consider this code:
void a_method() {
callToAnotherMethod(QRect(0,0,30,30)*);
}

In Eclipse, when the cursor is where I placed the * symbol above and I active the shortcut, a dialog shows up asking for the name of the local variable. Let's say I would enter "rect" and press ok, then Eclipse's JDK would convert the code from above to:

void a_method() {
QRect rect(0,0,30,30);
callToAnotherMethod(rect);
}

When evaluating the Nokia Qt SDK and writing my first Qt mobile app I had many situations, where I wished Qt Creator would know about [Alt][Shift][L], too.
