In X Rebirth, what is the key I can use to target the nearest enemy? I can't seem to find it in the control settings.
UPDATE: Patch 1.24 (2014-02-04) added new functions:
Manual target control with keys for target nearest crosshair, closest enemy and next/previous target. Further improvements planned.
Closest enemy can be selected by Shift+E, object near target reticle can be selected with Shift+F with default key bindings.
There is no in-game button for it at the moment, Egosoft promised to make it future patches.
But there is mod Targeting UI Extension now with External Camera.
Currently (this will change soon), Rebirth has no good way of targeting enemy ships. This mod, extends the UI by adding a targeting menu with keyboard selectable commands.
In addition, one of the commands will trigger an external camera view of the selected target. The duration of the full-screen view is 5 seconds and can be repeated for extended viewing.
