In Calc I can't use MAJ+CTRL arrow to select to the end automatically like in Excel

Hi, In Calc I can’t use MAJ+CTRL arrow to select a large part to the last input automatically like in Excel, for example, I want to remove the line 48918 with input N°48917 to 59101 with input N°59100, using MAJ+CTRL ↓… But it is not possible actually… Please add it.

What OS, what version of Libre do you use?

On my installation Shift+Ctrl+Arrow key does what I expect from it - it selects cells in the correct direction. So maybe you have a modified version, where some of those combinations are assigned to other functions. In Windows/Linux, handle that in Tools - Customize - Keyboard, on a Mac, you need the Apple menu on the far left of the menu bar instead of Tools.
In English the command you want is called Select to Lower Block Margin.
