If you hold down the Option key and choose Amplify > English Texts > KJVS, then it will search KJVS by key number instead of by word.
Now, by using System Preferences, you can create a keyboard shortcut for that menu item, and if you include the Option key in the shortcut, it will search by key number.
System Preferences > Keyboard > App Shortcuts
- Application: Accordance
- Menu Title: KJVS (any keyed text name which appears under Amplify > English Texts.)
- Keyboard Shortcut: ⌥⌘6 (Option-Command-6)
You can choose a different shortcut, but it must include the Option key. That is the trick.
Now when you press ⌥⌘6, it invokes the Amplify > English Texts > KJVS menu, and then Accordance notices that the Option key is down, so it does a key number search.
This was probably an unintentional feature, but I like it.
