Starcraft II – Burrowed Unit Selection and Zealot Upgrade
There are two upgrades possible at Twilight Council, one is researching ‘Charge’ for Zealots and the other is researching ‘Blink’ for Stalkers. Charge upgrade for Zealots includes movement speed increase of Zealots as well. So to speak, Charge increases the movement speed of Zealots AND allows them to intercept nearby enemies.
Unit Selection of Burrowed Zerg
However, for unit’s cloaking ability like Ghost and Banshee, I couldn’t swith off the selection of Cloaked/Decloaked units in one group by Tab key.
And one more thing, when you double click on a unit, you can select all of the same units even though some of the same units’ ability is on and other’s off like Siege Mode or Cloak. But you can select only burrowed or rooted units by double clicking on burrowed or rooted units.
I will check this more with Development team and if I have additional information on this, I will share it with you.
