As it needs 3 keys on a German keyboard (alt shift 7) to get a backslash, I would like to use the keys on the numerical keyboard to get this character (and others difficult to obtain as é). I tried two different versions of ~/Library/Keybindings/DefaultKeyBinding.dict
available at
http://alexanderstoffel.selfip.org/KeyBindings/DefaultKeyBinding1.dict
and
http://alexanderstoffel.selfip.org/KeyBindings/DefaultKeyBinding2.dict
After rebooting, the first version has the effect that hitting the corresponding keys does neither insert the former nor the desired character but the acoustic system alert is audible. The second version does not have any effect. How can I get the desired effect? I am using a MacBook Air with macOS Sierra (10.12.1) and with an additional Apple Keyboard (Product-ID: 0x0250).

Got this all from more recent Brett Terpstra posts, so full credit to him.
Using Karabiner Elements and BetterTouchTool, you can create a "Hyper" key mapped to control-option-shift-command (which probably won't be used by any apps as a default modifier). Then you can use BetterTouchTool to maps Cap Locks + "a" to type "=". Typing "a" by itself still gets the letter "a". You can also set it up that tapping Cap Locks alone functions as the escape key or even as standard Caps Lock.
Rather than reposting Brett's code here, I'll link to the post: A Hyper Key with Karabiner Elements, full instructions.
Some screenshots to help guide you along:
After adding Brett's code to karabiner.json, the Complex Modifications pane will look like so. No need to do anything else here.
In BetterTouchTool, switch to the Keyboard pane, add a shortcut, type Caps Lock + character, then choose "Insert/Type/Paste Custom Text" as the Trigger Predefined Action.
In the Insert/Type/Paste Custom Text sheet, type the character(s) you want and choose "Insert Text by Typing".
create a new user and login as that new user to see whether it works normally.
In my case, it works normally. Then check login items of the current user: Preferences > Users & Groups > Login items. Then remove unuseful items and relogin, remember to uncheck reopen windows when relogin.
Then, everything works normally. Thanks Nunzy in #MacOSX channel!
Thank you so much!!!

I haven't had much luck the keybinding dict route, seems very spotty what works and what doesn't. Far easier to use an app like Ukulele to make a tweaked keyboard layout exactly how you want it - no issues whatsoever. Much recommended.
