Tip 002: highlight method exit points

Also: record a macro that does "escape" then "ctrl-shift-f7" and
associate this macro to mouse click. Now when you click on any symbol
its usage is automatically highlighted.

Using Ctrl-shift-F7 you cna highlight usages of fields/methods/...
But it can even more. Being used on:
- "throws" keyword it shows all possible causes of any declared exception
- "return" keyword it shows all exit points
- "catch" keyword it shows all places where this exception is thrown in
the try-catch-block.

Very nice. Thanks.

Well.
In fact I noticed that when you do that, you can't make a mouse
selection anymore :(

I mapped mine to Shift+Click so it doesn't interfere with normal clicking.

Hi all,

in the following example, it works only for checked exception (`Ctrl +Shift + F7` on `catch` keyword). It actually doesn't work for `NoSuchElementException` here. Maybe this is because `iterator().next()` do not explicitly declare exception in `throws` clause but only in Javadoc. It might take into account the Javadoc `@throws` too:

public static void main(String[] args) {
    List<String> test = new ArrayList<>();

    try {
        String next = test.iterator().next();
    } catch (NoSuchElementException e) {
        e.printStackTrace();
    }

    StringReader ppp = new StringReader("PPP");

    try {
        int read = ppp.read();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
