In Sublime Text, it\'s easy to select the next instance of a word by pressing command + d and also place multiple cursors by pressing command & clicking
Highlight the word you'd like to get the next instance, then press:
⌘ + E
and
⌘ + G.
Continuing to press ⌘ + G will cycle through all instances of the word you pressed ⌘ + E on.
I have more xcode shortcuts on my site that I sometimes reference.
