Nsis to tray, to abort long...

How can I send an nsisMyApp.exe to tray to allow long operations executed in silent mode to be aborted at any time ?

Or
How can I abort a silent operation safely (instead of using Ctl Alt Del)

Or
When in silentinstall silent
Can I assign a hotkey to abort?

Or
Anything exept ctl alt del

If you mean the system tray, you can look at the NotifyIcon plug-in.
