I've assigned keys to each Dictionary view through System Preferences.
F2 for "Show Dictionary"
F3 for "Show Object Model"
F4 for "Show Explorer"
1) when I move from one view to the other, it takes a significant amount of time (like 1sec) to have the Tool Bar View buttons updated and display the actual state the Dictionary is at that moment
2) When I move to "Show Explorer", all of the view options are greyed out and the shortcuts won't work anymore, so I have to go to the Tool Bar and actually click on a button to change of view
3) I mentioned the access keys issue a while ago, but when I set the keys through System Preferences, I get F2/F3/F4 properly displayed as F2/F3/F4 in SD (even in the Key Bindings section of the preferences), but when I set the same key bindings directly in SD, they are displayed as F2/F3/F4 in that window, but as fn F2/fn F3/fn F4 in the actual menus.
