Edit: I went to keyboard settings and reconfigured the shortcuts.

My laptop specs are in my signature.

Specifications in signatures are pointless. They are rarely updated and do not provide sufficient information so most of the helpers here ignore them completely, as have I. To get the assistance you need, click the link at the top of the page where it says Forum rules Before you post please read how to get help. Please pay particular attention to section 5 and if you need to post the output from a terminal command, enclose it in code tags [code]output.here[/code].
