I need to rephrase this I think. What I meant was what keyboard shortcuts do the pros use most often because I do not use any. That is my main problem right now. Which shortcuts are redundant and which ones are absolutely critical.
shift - for the build orders (maybe no need to say this) alt + right mouse for attack move (important for engies to reclaim the map) ctrl + x for all units ctrl + a for all air units ctrl + l for all land units ctrl + b for all engies ctrl + k to kill the acu (very important)
K and L are near each other, best to either rebind one of them OR get suicide confirmation (UI mod). My ACU and/or army went up in flames several times due to mistypes.
Don't complain about that which you aren't willing to change.
This was my fourth match against a rank 1800!! He came in EXTREMELY fast with air. Was not real sure how to deal with it but still squeeked in the win. Is there a better def. for this opener?
