Why does LibreOffice select all text in between when using shift-select?

Hello, when I go to select two different lines of text (Ex: text from line 1, and text from line 5) it selects everything from line 1 to line 5.

I tried using ctrl+select, but it does nothing.

Because it is designed that way. If you want do multiple selection, use ctrl instead od shift.

Confirmed – can select multiple chunks from different lines using CTRL+ selecting with the mouse.
