Add support for multiple delete and keyboard assistance

[ghost]

Is any support planned for multiple select rows and delete them over the keyboard keys delete etc.? The same thing in the search box. Here it would be nice to hit enter and the search starts.

Great App =). I like it.

I was also going to submit a feature request for the "press enter to submit form" feature.

It would be really nice. Thanks.

First I intend to support the hit enter and search starts as #42
