[doc] native menu items documentation on linux is missing

[p32929]

Describe the bug

Hello, first of all, thank you for making and maintaining Tauri.
So, 've been making a test app using Tauri. but it seems, the CTRL/COMMAND + Z keyboard shortcut ( along with many other keyboard shortcuts ) stops working inside the app.

I also have added a menu like this one: https://github.com/windht/watcher/blob/bd929e555319c3e6c4565a2631b63a04918c03fb/src-tauri/src/main.rs

But it looks like this:

Any solutions? Thanks

Reproduction

1. create a tauri app with a text input within the app
2. write something in the app
3. now try to undo the text using keyboard shortcuts

Expected behavior

Keyboard shortcuts to work as expected inside the app

@team I asked for an issue about the undo/redo shortcuts only but thinking about it, we probably want to look at the MenuItems or at least their docs, since the latter doesn't seem to be accurate, many of them state that linux is supported (or at least don't say it is not supported) without actually working (that's why the menu looks like that, if you add an item that actually works it looks fine again).

[JonasKruckenberg]

So to understand this correctly, "builtins" for these common actions is just not a thing on Linux in general? Or it's just not widely supported/has a common standard behind it? Or is it just something we haven't gotten around to implementing yet?

[FabianLars]

No idea if your question is about the MenuItems or undo/redo not working, so i'll answer both.

MenuItems: tbh, no idea if we're talking about bugs or incorrect docs. Some of the (native) MenuItems specify that they don't work on Linux and they indeed don't.
Some others don't specify it but still don't work (see their linked example), while others work fine (Hide for example)

With "specify" i mean that they list Linux in the unsupported section.

undo/redo shortcuts: In tauri apps they generally don't work (no matter the distro) while it works fine in other gtk/webkitgtk based apps like epiphany (Gnome web). I didn't find much about webkitgtk in particular, but in gtk(3) in general it needs some manual implementation.

I believe only some macOS menu items implementation are handled by the OS; the others are all implemented by tao.

Just looked over the menu items you chose and:

• Copy, Cut, Paste and SelectAll are not supported on Linux yet, so we are missing documentation here.
• Undo and Redo for now are only supported on macOS and we documented that.
