Programmatically toggle theme

[gonstoll]

I almost always use a dark theme, but some times on some random moments of the day I need to switch to a light theme simply because there's too much light coming from outside, or other external circumstances. On other terminal apps I usually have a keymap for toggling a theme, so that I can do it at my leisure whenever I need to.

I know that ghostty has functionality for switching themes based on OS theme, but that's not precisely what I need, as my OS theme can be "light" but I still want a dark theme on my editor.

Is there a way to programmatically toggle a theme with a keymap?
