Overridding "Command-H" doesn't work on MacOS after migrating from 12.x to 13.x.

I used to have this config in my previous (12.x):

key_bindings:
# See https://en.wikipedia.org/wiki/C0_and_C1_control_codes for codes
- { key: H, mods: Command, chars: "\x08" }
...

I rebind most of Command+<key> to behave like Control+<key>, the above-mentioned control sequence allow to type Command+H for Emacs to open help, but now it's overridden to hide the window and seems like after migrating to TOML format of the config it didn't change:

[[keyboard.bindings]]
chars = "\b"
key = "H"
mods = "Command"

I am not sure what alacritty migrate does in this specific case.

Also, the following is broken:

  # Frequently, terminals send Ctrl-Space as Ctrl-@ and according to the wiki escape codes it is just '\x00'.
  # From that point, Emacs would recognized both Ctrl-@ and Ctrl-Shift-Space as the same.
  - { key: Key2,   mods: Shift|Command, chars: "\x00" }
  - { key: Space,  mods: Shift|Command, chars: "\x00" }

In 12.x, Command-@ (Command-Shift-2), used to work as well, but it doesn't work on 13.x anymore.

I am pretty sure there is a bunch of more broken bindings, it's just the beginning :)

But this, kind of weird, configuration works:

[[keyboard.bindings]]
chars = "\u0000"
key = "@"
mods = "Shift|Command"

where the following ones do not work as expected:

[[keyboard.bindings]]
chars = "\u0000"
key = "2"
mods = "Shift|Command"

[[keyboard.bindings]]
chars = "\u0000"
key = "@"
mods = "Command"

Seems like, now Alcritty requires the shift to be present in the character and modifier as well.

I was able to fix the broken Command-H with a hack from #6136, but having a custom binding for "Hide alacritty" on mac os level.

This one doesn't work as well:

[[keyboard.bindings]]
action = "IncreaseFontSize"
key = "Equals"
mods = "Control|Shift"

[sstepashka]

But after changing to this it works:

[[keyboard.bindings]]
action = "IncreaseFontSize"
key = "Plus"
mods = "Control|Shift"

Does it do both your custom binding and hide, or only hide?

[sstepashka]

Only hide.

I think the app menu stuff blocks it, so we'll have to communicate to e.g. winit to not provide menu items for such bindings or manually specify menu items based on the bindings we have.
