When the popup of the Combobox is opened and an item is focused, select its value on pressing Enter when using custom values:

I would like to be able to render the selected item for a ComboBox with a template which could be called kendoComboBoxTagTemplate so that I can render it as a hyperlink. This feature would provide similar functionality to the MultiSelect kendoMultiSelectTagTemplate.

I had considered doing a bit of a hack by using the MultiSelect and only allowing a single selection but this is nasty as you will still get the selected value as an item in an array. It would be much better if the tag template functionality was provided for ComboBox.

When ComboBox popup is closed and the cursor is in the input field, you can use arrow up and down to select next/prev item in the list.
Allow the use the mouse wheel to do that (only when combobox has focus)

This is mainly for kendo ui for angular.  The debounce property could be the number of milliseconds before the filter event is fired.  

A Telerik filter act as "contains" operator (probably 90% of use cases)
should be good to avoid writing everytime filter by hand 

Add sender to events, to reuse methods

=> ComboBox 

  valueChange(onlyValueNoSender) {

  }
