How to enable macOS keyboard shortcuts in Juno?

Question

I installed Juno on a Macbook Late 2007, and even enabling the "English Macintosh" keyboard, the shortcuts are not the same, for example CMD+C and CMD+V to copy and paste, and to enter Latin characters such as "éôãç..."

How can I resolve this?

Answer 1

I can address the copy/paste situation, but the Latin issue may require a more in-depth resolution that involves learning xkb and will be outside the scope of my answer as I have not worked that much with providing compose key or multi-language support.

For copy and paste to work with Juno or most any distro you can use xkeysnail or use my kinto app which will use either xkeysnail or xkb to setup keymap switching like you are wanting.

A short example of some remapping I do with it, but you will need the entirety of kinto if you want it to fully configure things for you as it will also setup xkeysnail as a systemd service, something xkeysnail will not do and the complete kinto.py config file will manage several different keymaps for the proper apps by default.

import re
from xkeysnail.transform import *

terminals = ["gnome-terminal","konsole","io.elementary.terminal","terminator","sakura","guake","tilda","xterm","eterm","kitty"]
terminals = [term.casefold() for term in terminals]
termStr = "|".join(str(x) for x in terminals)

define_conditional_modmap(lambda wm_class: wm_class.casefold() not in terminals,{
    # Default Mac/Win
    Key.LEFT_ALT: Key.RIGHT_CTRL,   # WinMac
    Key.LEFT_META: Key.LEFT_ALT,    # WinMac
    Key.LEFT_CTRL: Key.LEFT_META,   # WinMac
    Key.RIGHT_ALT: Key.RIGHT_CTRL,  # WinMac
    Key.RIGHT_META: Key.RIGHT_ALT,  # WinMac
    Key.RIGHT_CTRL: Key.RIGHT_META, # WinMac
})

# [Conditional modmap] Change modifier keys in certain applications
define_conditional_modmap(re.compile(termStr, re.IGNORECASE), {
    # Default Mac/Win
    Key.LEFT_ALT: Key.RIGHT_CTRL,   # WinMac
    Key.LEFT_META: Key.LEFT_ALT,    # WinMac
    Key.LEFT_CTRL: Key.LEFT_CTRL,   # WinMac
    Key.RIGHT_ALT: Key.RIGHT_CTRL,  # WinMac
    Key.RIGHT_META: Key.RIGHT_ALT,  # WinMac
    Key.RIGHT_CTRL: Key.LEFT_CTRL,  # WinMac
})

define_keymap(None,{
    # Cmd Tab - App Switching Default
    # App switching is mapped to use Ctrl+F13 in place of Tab
    # this avoids Alt+Tab from still activating App Switching
    # Ctrl+Tab is also used for In-App tab switching often times
    # RCtrl is also mapped in Cmd key position only
