In the Android SDK IDE, in the code view, if we bring the typing pointer at the location of a variable, all the other references to that variable gets highlighted, as shown
For some reason, this has stopped happening in my computer. It was enabled by default before, but suddenly it stopped happing, and I have no idea what caused it. If I hover the mouse pointer over a variable or class name it just shows the tooltip window, and if I bring the typing pointer at the variable's location then nothing happens. What is the name for this highlighting feature, and how do I re-enable it?
Incidentally, how do I view my android sdk version? The About ADT button says Build v22.0.1-685705, but the question tags here only show sdk2.1, 2.2 and 2.3, so i'm sure it hasn't reached version 22 yet. Or does this mean I have version 2.2?
