i can not understand this line {helpers:CommandBinding AddCommand}
the code is here :
<Window.InputBindings>
<KeyBinding Modifiers="Control" Key="E" Command="{helpers:CommandBinding AddCommand}"/>
</Window.InputBindings>
explain every markup in the above code:
if there is other option available then explain me .
That is a custom markup extension, which presumably returns a command. Ask whoever wrote it or if it’s part of some framework see the docs…
