Describe the bug / provide steps to reproduce it

Currently, when pressing alt-cmd-down which should add a cursor to the next line, or alt-cmd-up which should add a cursor to the previous line, it adds a cursor to the next or previous line with enough characters so that the new cursor falls into the same character index, which is frustrating to use.
