Function selection_movement

pub fn selection_movement(
    m: Movement,
    s: &Selection,
    view: &View,
    text: &Rope,
    modify: bool,
) -> Selection

Compute a new selection by applying a movement to an existing selection.

In a multi-region selection, this function applies the movement to each region in the selection, and returns the union of the results.

If modify is true, the selections are modified, otherwise the results of individual region movements become carets.
