Allow to disable Alt-Space opening menu on Windows

[bew]

Is your feature request related to a problem? Please describe. On Windows, Alt-Space opens a little menu windows with Restore, Minimize, Maximize, Close,... That menu is simply useless to me as I have many other ways to manage my windows more effectively.

I actually remember when you added the commit that 'restored' that behavior (it wasn't there at the beginning), and I remember thinking that that would annoy me one day. 👉 The day has come, I really want to use the Alt-Space binding in tmux/nvim configs when I'm ssh-ing to a server.

Describe the solution you'd like An option to disable this menu, or a way override Alt-Space keybind to act.SendKey{mods="ALT", key="Space"}.

Describe alternatives you've considered Using another key, but no 🙏

Additional context Nope

Hi Wez ;)

I'd really like to have this in short-med term, what do you think would be a way forward for this? Option? Keybind override?

I've never developed on windows, could you tell me if setting up wezterm dev on windows is a pain-in-you-know-what? Or if it's mostly straightforward?

wezterm dev on windows isn't too bad:

• You need to install strawberry perl (this is used by openssl's build system on windows)
• You need to install the msvc variant of the rust toolchain, NOT the gnu one
• Otherwise, https://wezfurlong.org/wezterm/install/source.html should work

This it the bit of code of interest:

https://github.com/wez/wezterm/blob/99c9613966a73d5388344fd0df68d5977b493c7c/window/src/os/windows/window.rs#L2839-L2846

There are a couple of ways to deal with this:

• Introduce a global config option to disable system alt-space and/or system alt-f4 shortcuts, by adding a conditional around the highlighted code to forward the message only when those option(s) are enabled. Then regular keybinds will work for those key combinations.
• Introduce a Windows-specific key assignment for showing the system menu (it's been a while since I've done this, I'd suggest searching along the lines of https://stackoverflow.com/search?q=win32+show+system+menu for examples of how to do it), then remove the code block I highlighted, and add default key assignments for alt-space and alt-f4 to show the system menu and close the window, respectively, to the list of defaults in https://github.com/wez/wezterm/blob/99c9613966a73d5388344fd0df68d5977b493c7c/wezterm-gui/src/commands.rs#L1970 and https://github.com/wez/wezterm/blob/99c9613966a73d5388344fd0df68d5977b493c7c/wezterm-gui/src/commands.rs#L616

Amusingly, this works just fine.

{
  key = 'Space',
  mods = 'ALT',
  action = wezterm.action.SendKey {
    key = 'Space',
    mods = 'ALT',
  },
},

But imo this is a workaround- a proper fix would probably let users use the more logical action = wezterm.action.DisableDefaultAssignment
