Note #2025-01-15-001

I had been facing an issue in #Emacs on my work Mac system: C-S-<tab> was somehow being translated to C-<tab>. I tried to look into key-translation-map to figure out the issue, but could not find anything.

Finally, turned out that I had bound C-<tab> to tab-line-switch-to-next-tab and C-<iso-lefttab> to tab-line-switch-to-prev-tab, but the actual C-S-<tab> was unbound. C-<iso-lefttab> only works on linux: something to do with how X11 sends the event to the application (and probably some compatibility mode due to which wayland was doing the same).

On Mac, once I explicitly bound C-S-<tab> in my Emacs config, it started working correctly.
