Enter a keyboard shortcut for Silence
There is a keyboard shortcut for tasks like autoheal and crop, yet there is not one for the silence which I use frequently.

There is no default keyboard shortcut for Silence, but Audition has an extensive keyboard shortcut editor where you can easily add one. Look under "Edit>Keyboard Shortcuts..." then search for Silence, and assign what ever keyboard shortcut you want.
