In the Motion 5.0.5 update that came out recently, kerning no longer works the same way. In previous versions, you would hold the Control key down and tap the left or right arrow keys while editing text to change the spacing between two letters. Since that keyboard combination is now used by the OS, there's a new way: hold down the Command and Option keys, and then tap the left or right bracket keys.
Thanks to Anders Larsen for this additional information:
A Danish keyboard doesn't have [bracket]-keys.
So for the hordes of Danish Motion users out there who use kerning all the time, here is a work-around:
- System Preferences -> Languages & Text -> Input Sources
- Make sure U.S. Extended is checked
- Click the Keyboard Shortcuts button and select Keyboard & Text Input
- Assign a shortcut to "Select next source in input menu" (at the bottom of the list)
You can now toggle between DK and US keyboard layouts and use the bracket key shortcuts for kerning. The Bracket keys are "å" and "^" (between "p" and the return key)
