To confirm a chosen menu item, use the C<Return> key.

In some submenus, it is possible to select more than one item before pressing C<Return> (e.g., the input filters
I<Choose Rows> and I<Choose Cols>); in such submenus, the list of items marked with the C<SpaceBar> is added to the
chosen items when C<Return> is pressed. If the mouse mode is enabled, you can use the right mouse key instead of the
C<SpaceBar>. Pressing C<Ctrl-SpaceBar> inverts the made choices - for example, to select all but one, select the one

The elements are right-justified if they look like a number; otherwise, they are left-justified.

If the option I<squash_spaces> is enabled, leading and trailing spaces are removed from the elements, and spaces are
squashed to a single white space.
