Menu & Search bar description change

Hi Zoho,

Is there any way to change the text content on the below red square highlighted below? 

For example I would like to change "Home" to "Helpdesk", "Knowledge Base" to "FAQ" and "Search our knowledge base or submit a ticket." to "Search our frequently asked questions or submit an enquiry".

Thank you in advance for your support, do let me know if there is any question.
