Can you bind next/previous window?

[mitsuhiko]

On macOS you can use cmd+`​ and cmd+shift+`​ to cycle between windows. This does not seem to be exposed to keybinds however or I'm missing something.

Basically looking for this:

keybind = super+right=next_window
keybind = super+left=previous_window

Is this possible today?

Not available. I'm open to doing this but I'm curious if macOS has an API to let you do this. Once I (or someone else) finds that, I can convert this to an issue, I just want to make sure it's possible. :)

I'm not sure if macOS has an API for this. I just looked at what iTerm2 does and they manually keep track of the terminal windows open: https://github.com/gnachman/iTerm2/blob/885a8a89146262de7f05a21ddf9bba935c35c7cb/sources/iTermController.m#L416-L446

I can't look at iTerm2's source since it's GPL. You're welcome to describe it to me (it sounds like you already did though).

I just asked ChatGPT if it has a better idea and it came up with this, which is similar in nature:

- (void)goToNextWindow {
    NSArray<NSWindow *> *windows = [NSApp windows];
    NSWindow *keyWindow = [NSApp keyWindow];

    if (!keyWindow || windows.count == 0) return;

    NSUInteger currentIndex = [windows indexOfObject:keyWindow];
    NSUInteger nextIndex = (currentIndex + 1) % windows.count;

    NSWindow *nextWindow = windows[nextIndex];
    [nextWindow makeKeyAndOrderFront:self];
}

- (void)goToLastWindow {
    NSArray<NSWindow *> *windows = [NSApp windows];
    NSWindow *keyWindow = [NSApp keyWindow];

    if (!keyWindow || windows.count == 0) return;

    NSUInteger currentIndex = [windows indexOfObject:keyWindow];
    NSUInteger lastIndex = (currentIndex == 0) ? windows.count - 1 : currentIndex - 1;

    NSWindow *lastWindow = windows[lastIndex];
    [lastWindow makeKeyAndOrderFront:self];
}

Keybindings to jump next/previous in tabs and windows is likely the feature I use the most in wezterm. It isn't apples to apples, wezterm being written in rust, but it is an MIT license.

Not pertinent to the discussion, though the name, logo, and icon for the project are fantastic.

This would be very helpful to add, since I cycle through windows of terminals a lot (cmd+<, cmd+>) and default keybindings in mac OS for cycling windows is really bad for a default german keyboard layout (backtick which is a deadkey).
