Backslash cannot be inserted in Sublime Text 3

Question

I am using Sublime Text 3 for Windows with a German keyboard. A backslash is \assigned alt gr + ß, but this key binding does not work properly. (The cursor increases by several lines.)

Since it is alt grequivalent ctrl+alton Windows, I added the following line to sublime-keymap.

{ "keys": ["ctrl+alt+ß"], "command": "insert", "args": {"characters": "\\"} }

But that doesn't work either.

Can I appoint \ alt gr+ß?

Note:

• "keys": ["ctrl+alt+0"](instead "keys": ["ctrl+alt+ß"]). But I want to use "alt gr + ß" for the backslash.
• "keys": ["ctrl+alt+\u00DF"] does not work.

Answer 1

The following settings work fine!

In Preferences→Key Bindings

{ "keys": ["ctrl+alt+["], "command": "insert", "args": {"characters": "\\"} }
