Is there a way to only execute the command one time when you hold the keybind?

I have Ctrl+S keybind which saves the file currently opened in the editor. When I hold the keybind, it starts repeatedly saving the file. Is there a way for it to not do that?
This is the code I'm using:

editor.commands.addCommand({
    name: "save",
    bindKey: { win: "Ctrl-S", mac: "Cmd-S" },
    exec: (editor) => {
        saveFile();
    },
});

Ace does not have a way to register commands only for key down, but one workaround is to use

if (window.event && window.event.repeat) return

before calling saveFile,
That said, i think most editors simply use save state to prevent repeated calls and don't distinguish between first and repeated calls.
