Sending email inadvertently with keystroke(s)

Sending email inadvertently with keystroke(s)

Hello, I'm having a problem when I'm composing an email in Zoho that when I inadvertently hit a combination of keys, the send function is triggered and the email is sent off without me finishing it. Question is what keystrokes am I hitting that is triggering the send function without me clicking send once I'm ready to send. Thanks!
