Normally F4 & Shift + F4 are used for cycling through found results. But if you set your cursor position to one line upper of what you want to go and press F4 it opens the file and sets your cursor position to start of that line.
And if you want to change shortcut put this in your "Default (OSX).sublime-keymap" file in User directory and change F4 to shortcut you want:
{ "keys": ["f4"], "command": "next_result" }
Edit:
Just noticed Shift + F4 goes to right result (as long as cursor is not at first column of line. In that case previous result shows up) even if your cursor is 'at' the results itself. So that's better for this question.
Second edit:
"User" directory is "/Users/Username/Library/Application Support/Sublime Text 2/Packages/User" which also can be accessed through Sublime Text 2 (Command Palette (Super + Shift + P) or through menu (Sublime Text 2 > Preferences > Browse Packages...))
