One-Way vs Mutual Links

If a link only makes sense ‘from’ one concept ’to’ another, the default ‘One-Way’ link will do.

If instead each concept is linked in the same way to each-other, you can switch it to a ‘Mutual’ link. Simply select the link you want to switch, and look in the context pane for the ‘One-Way’/‘Mutual’ toggle. Selecting ‘Mutual’ will make the arrow shown on the default link disappear.

If for whatever reason the link is switched back to ‘one-way’, it will retain its original direction.
