I think vwanweb is right. But I'm a bit confused by "top", "bottom", "lower", etc. If you mean the red one is on the bottom, vwanweb is right (and the resulting red "L" would be upside-down). But the red one is at the top of the page, and if you want a blue, rightside-up "L", you'll need to change the z-order of the squares.

that is kinda what i am looking for but when i tried it it worked but the blue square was gone - i am looking to keep both there but just adjust the nodes --

drynn: yes i didnt mean the top of page color i ment top layer - i want the red to be an "L" shape side ways and still keep the blue intack

No such functionality exists in Inkscape yet, but someone could easily write an extension for it. (Hint)
The workround is to select the top shape, copy to the clipboard, then select all, do 'ctrl + -' that's the 'difference' - and then paste back in place (ctrl + alt + v)
A long time ago Illustrator had a 'pathfinder' operation called - I think - 'remove hidden,' that would do exactly this - in order to reduce file size. Maybe it still does.
Your mind is what you think it is.

I use a similar approach to druban's suggestion, but without using the clipboard:

1) Select the top item (blue in this case).
2) ctrl+d to duplicate it in place. That leaves the new copy selected.
3) Shift-click on the bottom (red) object to add it to the selection.
4) ctrl+- (I use the minus on the numeric keypad) to perform the difference operation.
