[SOLVED] Selecting a range of cells LO Calc vs. Gnumeric

In Gnumeric, if I have a block of cells of unknown length, all of which contain values, and I want to select all cells from the current cell (somewhere in that block) to the last cell. I just hold down the Shift key and press End Down-Arrow. But I can't for the life of me figure out how to do the same selection with a couple of keystrokes in LO Calc. What am I missing? Thanks.
