How do you unselect objects?

I remember reading a while ago that there was a way to unselect everyone so that you are not targetting anything. The use of this would be in cases where a monk would want to heal party, but there is something preventing him/her from doing so, such as Kanaxi's aspect of failure...I think. I may be way off on this though.

Can anyone shed some light? Or am I just rambling a bunch of nonesense

The only way I de-select things is by pressing 'F' and targetting myself. I'm not sure of any other ways .

Normally you just hit tab when no enemies are around, but obviously that wouldn't work in The Deep <_<

I dont know how not targeting anything would make you able to cast under Aspect of Failure though, If it does it is a bug because the aspect stops the usage of ALL spells in its range, nomatter who they target.

Heal PArty is easy enough to use around The Deep because of its range though..
