The delete command behaving weird!

So the delete command doesn't delete anything that is already selected when activated.
Eg:
> Select elements
>type "er" in command line
>press space/enter
>nothing happens - the command line says "select items to delete"

This is kind of annoying, even if you type the command first, cannot box select items.
Eg:
>type command "er"
>press space/enter
>Can't click and drag, have to select lines one by one!!!!!!!!!!!

Please fix this.

Please change your habits.

Not everything in LibreCAD works, works well or works like in AutoCAD.

The easiest way to delete something in LibreCAD is to select one by one or with a box and then simply press the Delete key. Gone!
