super+c not working on Mac

The bug

First, thanks for this amazing library.

Entering command+c does nothing on Mac (for me at least). Tried in both iterm and VSCode terminal. Confirmed by running textual keys and entering command+c, which does not register as an event.

From the recent release, my understanding was that the super+c binding added to various widgets should enable copying of text using the normal command+c combination on Mac, but doesn't seem to be the case

command+c is simply not sent to the app by the majority of terminal emulators, as it is used for system copy to clipboard. Ghostty is a little smarter, it sends cmd+C when in application mode. Other terminals may follow suit in the future. Until then you can use ctr+C to copy.

Just realized that this happens because the terminals I tested literally don't send the signal. Checked on Ghostty and it works

For my understanding, so I can potentially investigate workarounds for my application (assuming this isn't solvable in general within textual), is this happening because command+c to copy on Mac doesn't interact with the application at all, but just maintains a system-level "selection" which is put in the clipboard on command+c, and when using textual, it prevents anything being truly selected from the OS perspective?

EDIT: thanks for the super fast reply @willmcgugan - saw your comment 1 second after replying

If it's useful information, here's a bit more info about coverage for this in terminal emulators (each with default configuration, some may allow it in the config somewhere but not sure):

• iterm: does not send super+c
• vscode: does not send super+c
• ghostty: sends super+c
• kitty: sends super+c
• Alacritty: does not send super+c
• wezterm: does not send super+c
