Absolutely- go to references or find references is the other half of having a "go to definition feature". I am looking at MonoDevelop right now, and right clicking on a symbol in code brings up this contextual menu:
Go to declaration // Sublime has this
Go to base
Find derived classes
*Find references* // this is missing from Sublime
Edit: in fact there is a menu item for "Go To Symbol in Project" in Sublime, but as far as I can tell it goes to the Definition, and does not present a list of occurrences/references/usages of that symbol.
