You
can determine the hot key assigned to a button from anywhere within Smoke.
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.
