called targets

I am having touble using the keyboard for called target. Can someone just briefly tell me how it works? I know how to cycle through targets using the TAB, but

1) how do you just use the keyboard to call a target (I think its T)

2) as the caller, how do you then attack the called target (is it spacebar)

3) as a non-caller, how do you attack the called target and how do you know which is the called target. Thanks.

cant help on the first two as i use the mouse (ctrl-double click the name to call that way) but yes, to attack the called target you press ctrl-t

to call a target you have selected press ctrl+space

to attack a character you have selected press space

Their is a thread a.bout commands but i cant seem to find it evidently its not stickied anymore

Thanks. As a non-caller, how do you attack the called target and how do you know which is the called target. (not using the mouse)

To call a target, use CTRL-Space or CTRL-Double Click.
To start attacking a called target, use "T".
