Same inconvenience here. I use "Crop & Zoom" very often, in order to rotate my clips when the horizon is slightly tilted (it happens a lot!). In order to just reach "Crop & Zoom", I need to click 4 times at various screen locations. This makes my editing process very tedious (sometimes I have to correct the tilt of more than 50 clips !)
Unfortunately, Power Tools items cannot be acced via keyboard keys anyway. Therefore a keyboard remapping utility (like AutoHotKeys) would be useless here.
I noticed that the custom hotkeys feature uses .pdh (xml) files and I wonder if we could make use of it. The following example maps key "C" (VirtualKey 67) to "Link/Unlink Video and Audio" command ( Key Index 109):
<!--?xml version="1.0" encoding="UTF-16"?-->
<hotkey><set name="test2"><key index="109" controlkey="0" virtualkey="67"></key></set></hotkey>
If we knew the "Key Index" of the Crop & Zoom command, we could map it to an unused key combination and import to PowerDirector via a similar .pdh file. Anyone with such an inside information?
