Is it possible to make delete to remove the selected items from the play list?

Thanks!

It works fine here. Which foobar and Columns UI versions you're using? And is your playlist locked in some way?

0.9.5.2

ColumnUI 0.20

Make sure that your delete key is bound to remove.
When I dl'd foobar once, there wasn't a keyboard shortcut for delete...

Maybe u're trying to remove something from autoplaylist? I guess its not possible ATM.

You're correct. Another explanation could be a "read only playlist".

When I try to add delete key, I got the following warning:

mapping this key interfere with app functionality, overriding editing/navigation controls

Is this normal?

yes, in new versions of foobar (since 0.9.5 IIRC) hotkeys take effect even in places such as the search window so generally single key hotkeys are not a good idea however I don't know about you, but I don't use the delete key when I type so it shouldn't be a problem
