My experience on MacOS is that every program has different shortcuts regarding text editing. Home/End/PgUp/PgDn on my external keyboard just not working, and if added to system settings, they still don't work in some apps, Ctrl+Left sometimes working sometimes not, etc.

And what Ctrl/CMD/Shift keys do together looks very random, no logic in it. Like, Ctrl+Left in Zsh scrolls the entire log to top, rather than move the cursor to the start of the line.

I use zsh, slack, Chromium, SublimeText and Zed on Mac.
