I'm trying to use the trial version of build 2097 on OS X 10.6.8. I cannot get the keyboard shortcut for auto-complete which is ^SPACE to work.Any ideas?
It's possible ctrl+space is intercepted before it gets to the application. For example, it's possible to have ctrl+space interact with Spaces.
Rather than digging around in your system settings, it may be simpler to just rebind it to another key.
Control-Space is reserved by OS X for changing keyboard layouts. Unintuitively, you have to enable the feature to disable the keyboard shortcut (and free up the key combo). To do this:
Go to System Preferences > Language & Text > Input Sources
Check (turn on) at least two input sources in the left column
Click the "Keyboard Shortcuts..." button in the right column
Select Keyboard & Text Input on the left
Scroll to the bottom and disable "Select the previous input source -- ^Space" on the right
Go back to System Preferences > Language & Text > Input Sources
Turn off the inputs on the left
