You’ll see from the 1password support site that there is a bug having to do with resetting the default shortcut keys. There are two versions of 1Password, one installed from their website and one installed from the app store.
If you use the one from the app store, you an delete these two files to reset all the preferences:
Folder: ~/Library/Containers/com.agilebits.onepassword-osx/Data/Library/Preferences/ Files com.agilebits.onepassword-osx.plist com.agilebits.onepassword-osx.plist.lockfile
ps: You may want to make a backup of these.
If you’ve downloaded the program from their website, you will find the plist file located instead at:
You can also open these 1Password plist preference files with a program like
PlistEdit Pro.app and simply find the following two values and delete them:
ShortcutRecorder bookmarks ShortcutRecorder restoreForm
