How do I transfer Klay?

I'm interested in learning more about transferring KLAY tokens. Could you please explain the process step-by-step? What kind of wallet do I need to have in order to initiate the transfer? Are there any fees involved? How long does the transfer usually take? Is there a limit to how much Klay I can transfer at once? And lastly, are there any security measures I should take to ensure the safety of my Klay during the transfer process?
