CMD + Delete

In Minecraft on macOS, pressing option and backspace deletes a single character, and pressing command and backspace deletes a word. This is completely inconsistent with the native OS, so I fixed it:

Not only does CMD + Delete fix the macOS text behavior, it also expands Minecraft into a fully user-configurable text editing/navigation shortcut framework!

Important Context

1. If you use this mod on Windows or Linux, and you don't use custom mappings, nothing will change from vanilla Minecraft.
2. If you have any problems with this mod, please report them as Issues on GitHub. This mod is Open Source and Pull Requests are very much welcome! :)

Custom Mappings

You can define your own custom mappings in configuration files with the location & name: <minecraft install>/config/cmd_delete/mappings/<id>.json. These allow you to customize the text navigation shortcut behavior in Minecraft for your own taste & configuration.

Features

Custom mappings can:

• Use wildcard expansion where any modifier not included in a key combo is treated as true OR false.
• Use friendly keyname strings defined by CMD + Delete instead of GLFW keycodes. If a keyname is not defined, you can still choose to use a raw GLFW keycode in your JSON.
• Inherit keybinds from the builtin mappings or other custom mappings by setting the top-level inherits value to custom:<id> to inherit a custom JSON, or builtin:<id> or just <id> to inherit a builtin JSON.
• Patch & override the mappings they inherit by setting the keybind to have enabled property as false. Note that CMD + Delete always removes your disabled keybinds before adding your enabled keybinds, allowing a patch-then-reimplement pattern to be easily done.
• Set certain boolean feature flags to control the mod's behavior.

Note that:

• The format version fv is currently 3 and your mappings should match that (Though old mappings of format version 2 are still supported in-game).
• The meta.id field must exactly match the filename without the .json extension

The /navmappings command

CMD + Delete includes an in-game, client /navmappings command for checking, switching, importing, exporting, and debugging mappings without manually touching config files.

Here are all the subcommands:

• /navmappings info: displays info about the currently loaded mappings.
• /navmappings list: displays a list of the namespaced IDs of the currently available mappings, which you could switch to.
• /navmappings set default: switch to the default mappings behavior.
• /navmappings set builtin <non-namespaced id>: switch a specific OS's builtin mappings JSON.
• /navmappings set custom <non-namespaced id>: switch to one of your own custom mappings JSONs.
• /navmappings reload: reload the currently active mappings.
• /navmappings export <type> <non-namespaced id> <absolute location>: make a copy of a mappings JSON to another location on your system so you can copy it.
• /navmappings import <non-namespaced id> <absolute location>: import a copy of a JSON you made from another location on your system into the custom JSONs folder for you to use as custom mappings.
• /navmappings debug: a utility that provides dumps of information like info about CMD + Delete, a dump of the friendly keynames which CMD + Delete mappings JSONs support, or a raw dump of the internal loaded mappings' registry.

Builtin Mappings' Shortcuts

By default, CMD + Delete will detect if you're using macOS, and if you are it'll set you to those shortcuts, otherwise it will set you to use Windows/Linux shortcuts.
