Are you talking about tmux? Remap to Ctrl+Space. Ctrl+B is one of the worst defaults I could imagine. I wonder if they did it just because it's one higher than Ctrl+A from screen (which was much easier to type).

If you're not talking about tmux - also consider remapping if possible.

I remapped tmux to control-\ (which didn't conflict with anything in emacs that I cared about). It kind of sucks to hit that in a non-tmux shell or one without my config file though ;).

Control-space is mark in emacs (even though I am using vscodium these days - I do fire up mg for quick things). It does make it a two handed chord (left control) but it's quite fluid for me.

Ctrl+Shift combos without Fn remap is even more impossible with some other locale keyboards, e.g. the nordic layout: https://laptops.fi/wp-content/uploads/2021/06/63Y0145-scaled...

You're doing it wrong. C+S+b is hit with the right Ctrl,Shift. Using the opposite-hand modifiers keeps your hands happy, and makes things fast.
