Align Left Keyboard Shortcut Stopped Working (and how to fix it)
There has been a rash of hijackings amongst Macintosh InDesign users who have upgraded or are using the latest version of the Macintosh OSX 10.8 (known as Mountain Lion). Specifically, the tried-and-true keystroke for aligning text to the left—Cmd-Shift-L—had stopped working. Align Right and Center are fine. But Align Left lost its keystroke.
Fortunately, the culprit was discovered to be lurking in a hidden corner of the Keyboard System Preferences.
If you have experienced this problem, here's how to fix it:
Open your System Preferences by going to Apple menu > System Preferences and then clicking the Keyboard icon.
This opens the Keyboard Preferences area. Click the tab for Keyboard Shortcuts and then click Services. Finally, scroll down for the Search With Google section under Searching. You'll see that Cmd-Shift-L has been assigned to that command and is interfering with InDesign's Align Left command.
Click to highlight the offending keystroke.
And then delete what's there! (Alternatively, you can turn off the checkbox to the left of the command.) Of course if you absolutely need a keystroke to search with Google, you can enter a new one. Just be sure it doesn't conflict with some other InDesign keyboard command.
That's it! You've just brought Cmd-Shift-L back into the InDesign family of shortcuts.
