If you feeling pressing TAB like a chore for scanning enemies around, I have an interesting solution for you.
You have an option to bind you Ecive to Jump button, so you gonna "press" both at the same time.

1. Press WIN+R
2. Type %appdata%
3. Go to \AppData\Local\M1\Saved\Config\Windows
4. Open GameUserSettings.ini
5. Find a string saying: "KeyInput=(BattleKey=Detecting,MainKey=(Chord=(Key=Tab"
6. Replace "Tab" with "SpaceBar"
7. Save file and make sure to check "Read-only" in files properties
8. Done.
