If you start a Hotkey Helper search with the ^ symbol (SHIFT + 6 on your keyboard), the Hotkey Helper will search application names rather than hot key descriptions. So the search phrase ^adobe will list all of the available hot keys in Adobe Reader.
To show all available hotkeys, enter ^* (SHIFT + 6, followed by SHIFT + 8 on your keyboard).
The results of your search are presented in tables. You can use your standard web browsing keys to review the results in the Hotkey Helper HTML window.
Your results are specific to your product version and current hotkey set.
