Macintosh OS X supports the ability to extend the default set of keyboard shortcuts for pretty much any application. Enhancing these shortcuts to map to menu items which you use frequently in FileMaker can significantly improve development time. Remember, muscle memory is better than mousy memory (because computer mice aren't really that smart).
While setting these shortcuts within the System Preferences is easily accomplished on one machine, these same settings cannot be transfered to another machine because they are stored within FileMaker's application preferences (e.g. com.filemaker.client.advanced.plist within ~/Library/Preferences/)
The solution is to maintain a preferred collection of keyboard shortcut mappings within a FileMaker file and simply install the enhancement on the running target machine. The file attached to this page does exactly this.
Downloading: You can download the file by clicking the paperclip icon at the top of this page.
Caption: Clicking the "Set Keys" button will insert your keyboard shortcuts into the NSUserKeyEquivalents entry within FileMaker's preference file.
Caption: The System Preferences Keyboard Shortcuts is where the keys will show up. You may need to come here in order for mappings to take effect if FileMaker is still running.
