# TOP SECRET
# CodeNight CodeKnight Answer Key!!!

# Problem 0
# Use Enumerable.each to print out a string for each knight in the format of "Jason prefers a sword"

knights.each {|knight| puts "#{knight.name} prefers a #{knight.preferred_weapon}"}

# Problem 1
# Use Enumerable.find_all to find all knights with 50 or more health

My stuff is all based off the Xcode keymap—it helps you start with a little bit of familiarity.

Run is weird in appcode, cause it doesn't hit the breakpoints like Xcode's run does. What you want is Debug.
I have mapped Debug to ⌘+R, and Debug... to ⌘+⇧+R (Debug... is awesome!) (Also if you hold shift when you are in the Debug... menu you can run instead of debug)

I have remapped ⌘+T to Class... Effectively this allows me to open new tabs a la Sublime style where you hit command t for a new tab, and then enter the class name you want to open in that tab.

I don't like a lot of the ⌘+1 through ⌘+9 windows the way they are. I picked the ones I like and then remapped them to the lower keys for the ones I like to use a lot. I also hid all the tool window bars.
