CMD + Delete

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

This mod also functions as a fully configurable text editing/navigation shortcut framework for Minecraft with custom mappings JSONs and sharecodes, in-game switching, and more!

Some 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! :)

Note:

CMD + Delete is a Fabric mod which also supports Quilt for Minecraft 1.16 to the latest version.

It also supports Forge 1.20.1 and NeoForge 1.21.1, but only with Sinytra Connector.

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.

Action	macOS	Windows / Linux
Delete previous word	option + backspace	ctrl + backspace
Delete next word	option + delete	ctrl + delete
Delete to start of line	cmd + backspace	N/A
Delete to end of line	cmd + delete	N/A
Move to previous word	option + ←	ctrl + ←
Move to next word	option + →	ctrl + →
Move to start of line	cmd + ←	home
Move to end of line	cmd + →	end
Move to start of text	cmd + ↑	ctrl + home
Move to end of text	cmd + ↓	ctrl + end
Select to previous word	option + shift + ←	ctrl + shift + ←
Select to next word	option + shift + →	ctrl + shift + →
Select to start of line	cmd + shift + ←	shift + home
Select to end of line	cmd + shift + →	shift + end
Select to start of text	cmd + shift + ↑	ctrl + shift + home
Select to end of text	cmd + shift + ↓	ctrl + shift + end
Select up one line	shift + ↑	shift + ↑
Select down one line	shift + ↓	shift + ↓

Other Builtin Mappings

CMD + Delete also now provides these other builtin mappings:

• builtin:emacs_windows_linux the standard Windows/Linux shortcuts for text navigation in Emacs to the best replication I can make (they're not perfect).
• builtin:emacs_mac the standard macOS Cocoa shortcuts for text navigation in Emacs to the best replication I can make (they're not perfect).
• builtin:readline the standard shortcuts for text navigation in GNU Readline to the best replication I can make (they're not perfect).

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. You can also easily share your mappings via sharecodes!

Technical 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.
• Enable strict mode (as a top-level JSON boolean) which would prevent your mappings from loading if they have certain recoverable issues like keybind conflicts or unknown actions.

Note that:

• The format version fv is currently 4 and your mappings should match that (Though old mappings of format versions 2 and 3 are still supported in-game).
• The meta.id field must exactly match the filename without the .json extension
• In some places, you'll see a mappings id of "" (empty string), that refers to the default mappings behavior of loading either builtin:windows_linux or builtin:mac depending on the user's OS. Note that "inherits": "" means a mappings JSON does not inherit anything, so it is impossible to inherit from the default behavior.
