Would be great to be able to directly enter the expression editor from a keyboard shortcut when using the "Assign" Pad on the right side of the screen.
Currently you need to scroll to the bottom to see the expression editor option.
Hey Mark,
To be consistent with Windows applications, if you click F4 it will open the dropdown of your property with all the suggestions. So, pressing F4 then Down and Enter will open the Expression Editor.
Hope this helped,
Cheers!
