This is simply a wrapper around @gkz's grasp. It was inspired by @janhancic.
When it's complete, everything that works for grasp should work from here. At the moment, the only thing that works for sure is searching for things.
You can follow the development of grasp here.
You must be in a javascript file, as grasp currently only supports javascript.
The current key binding is ctrl+shift+g.
This will bring up the input panel on the bottom awaiting your grasp command.
You can enter things like if.test to select all of the conditional tests.
Or return.arg to select all of the arguments being returned.
Just search for grasp.
