Same! A couple of my super-short must-haves are:

  ; Map CapsLock key to Control
  CapsLock::Ctrl

  ; Ctrl + Alt + Arrow key jumps to beginning/end of line/document; 
  ; Add Shift to select as well
  ^!Left::SendInput, {Home} 
  ^!Up::SendInput, ^{Home} 
  ^!+Left::SendInput, +{Home} 
  ^!+Up::SendInput, ^+{Home} 
  ^!Right::SendInput, {End} 
  ^!Down::SendInput, ^{End} 
  ^!+Down::SendInput, ^+{End} 
  ^!+Right::SendInput, +{End}

On any PC without these running I feel hobbled. It's like my shoelaces are tied together or something.
