Multiselect for terminal

I just seen a video about terminal in facvebook.
That seems a nice time saver.
I would love to see an emmet suport and “short acces” to the functions.
For example:
“.my-class” to add a class (in the video we see how you pick “add class” to do that)
“-.my-class” to delete it

In addition (and here the feature request) will be perfect thaqt we can select multiple elements in the panel.
