Help with putty window setting

hi friends,
This is not a shell scripting related doubt, but still posting so that you can answer it ;) or redirect to correct place in this website.

Many a times i have to open multiple putty sessions by duplicating a session and want to rename their tabs.

For this activity i have to right click(using mouse) on the topmost tab of the putty window. (Attached snapshot of the same)

Can you please suggest a keyboard shortkey for the same?

Regds,
Kunwar
