Keynote keyboard shortcut to navigate between objects on a slide

Pressing ⌃⌘+ or ⌃⌘- again seems to remove superscript or subscript in Keynote '09.

Other applications like TextEdit raise or lower the text multiple times though.

You could give custom shortcuts to nested menu items on 10.7, but it stopped working on 10.8.

Another option would be to create ~/Library/KeyBindings/ and save a property list like this as DefaultKeyBinding.dict, but it doesn't seem to work in iWork applications.

{
    "^@=" = unscript:;
}

You could also assing a shortcut to a script like this:

try
    tell application "System Events" to tell (process 1 where it is frontmost)
        click menu item "Use Default" of menu 1 of menu item "Baseline" of menu 1 of menu item "Font" of menu "Format" of menu bar 1
    end tell
end try

I was going to ask the same thing for Keynote 6 under 10.10, but I'll chime in here instead..

MacLemon's answer doesn't do anything helpful for me in Keynote on Yosemite.

One can switch between Navigator and Slide Only from the View menu (so shortcuts could be created via System Preferences), but:

• I can't find out how to leave the Navigator visible but change focus
• When the navigator is displayed, it doesn't get focus :(

There's a list of shortcuts here, but I can't find anything relevant..

Maybe an applescript / automator solution could be concocted.
