I've always found menu accelerators odd.

I find them a little too dependent on individual app developers word choices to have any kind of consistency across apps I use, plus I tend not to use menus for anything other than infrequent settings changes. Given that they haven't seemed substantially different to macos displaying annotations for bound shortcuts within the menus.

(admittedly I use mac in work & my personal computers at home have all been Linux since my Windows 2003 workstation died, so my knowledge of modern windows apps & their attached accelerators is rusty & I'm probably biased here)

The last windows I used was XP. But accelerators do work in Linux.

And they are not just about menus: in any modal window I can do Alt+O for Ok. And this paradigm allows discoverability, I don't need to memorize shortcuts, I just hold Alt and look for underscored letters – that's how GUI should be IMO.

It's not perfect, and if I were designing UI from scratch, I'd made this feature modal instead of allocating entire physical key for that (like they do hints in vim-like browsers).
