You
can determine the hot key assigned to a button from anywhere within Inferno.
To
determine the hot key for a button:
If
auto display of tooltips is enabled in the Preferences menu, hover
over the button for which you want to determine the assigned hot key.
If you have disabled the auto display of tooltips, press and hold Alt+Ctrl+spacebar and hover over
the button.
If a hot key exists for the button, it is displayed
in the tooltip.
